Answer: A
Solution: Key idea: This is a weighted average and linear transformation question, recognisable because it gives a frequency distribution (bar chart) and asks for the average of a linear function of the variable.
Step 1: Calculate the total number of patients across all shifts. From the chart: (5 * 20) + (6 * 40) + (7 * 30) + (8 * 10) = 100 + 240 + 210 + 80 = 630.
Step 2: Calculate the average number of patients per shift, \bar{X}. \bar{X} = 630 / 100 = 6.3.
Step 3: Apply the linear transformation for earnings. The average earnings per shift is 1000(\bar{X} - 0.2).
Step 4: Substitute \bar{X}: 1000(6.3 - 0.2) = 1000(6.1) = 6100.
Answer: A
Q2. (CAT 2026) The number of bijections \(f(\cdot)\) from the set \(S = \{1, 2, 3, 4\}\) to itself such that \(f(f(n)) = n\), for all \(n \in S\), is __________ . (Answer in integer)
Answer: 10.00
Solution: Insight: The condition $f(f(n)) = n$ defines an involution, meaning the permutation consists entirely of 1-cycles (fixed points) and 2-cycles (swaps).
Exam route: Use the involution recurrence $I(n) = I(n-1) + (n-1)I(n-2)$. With $I(1)=1$ and $I(2)=2$, we get $I(3) = 2 + 2(1) = 4$, and $I(4) = 4 + 3(2) = 10$.
Learning route:
We classify the bijections by their cycle structure for $n=4$:
1. Zero swaps (4 fixed points): There is exactly $\binom{4}{0} = 1$ way.
2. One swap (2 fixed points): Choose 2 elements to swap out of 4. This is $\binom{4}{2} = 6$ ways.
3. Two swaps (0 fixed points): Choose 2 elements for the first swap ($\binom{4}{2} = 6$), and the remaining 2 form the second swap ($\binom{2}{2} = 1$). Since the two swaps are indistinguishable, we divide by $2!$. This gives $\frac{6 \times 1}{2} = 3$ ways.
Total involutions = $1 + 6 + 3 = 10$.
Common Trap: Forgetting to divide by $2!$ in the two-swap case leads to $6 \times 1 = 6$ ways, incorrectly totaling $1 + 6 + 6 = 13$.
Verification: The recurrence $I(4) = I(3) + 3I(2) = 4 + 3(2) = 10$ perfectly matches the manual enumeration.
Q3. (CAT 2025) A \(4 \times 4\) digital image has pixel intensities \((U)\) as shown in the figure. The number of pixels with \(U \leq 4\) is:<br/><br/> <svg width="180" height="120" viewBox="0 0 180 120" xmlns="http://www.w3.org/2000/svg"> <rect x="30" y="10" width="120" height="80" fill="white" stroke="black"/> <line x1="60" y1="10" x2="60" y2="90" stroke="black"/> <line x1="90" y1="10" x2="90" y2="90" stroke="black"/> <line x1="120" y1="10" x2="120" y2="90" stroke="black"/> <line x1="30" y1="30" x2="150" y2="30" stroke="black"/> <line x1="30" y1="50" x2="150" y2="50" stroke="black"/> <line x1="30" y1="70" x2="150" y2="70" stroke="black"/> <text x="45" y="25" text-anchor="middle" font-size="14">0</text> <text x="75" y="25" text-anchor="middle" font-size="14">1</text> <text x="105" y="25" text-anchor="middle" font-size="14">0</text> <text x="135" y="25" text-anchor="middle" font-size="14">2</text> <text x="45" y="45" text-anchor="middle" font-size="14">4</text> <text x="75" y="45" text-anchor="middle" font-size="14">7</text> <text x="105" y="45" text-anchor="middle" font-size="14">3</text> <text x="135" y="45" text-anchor="middle" font-size="14">3</text> <text x="45" y="65" text-anchor="middle" font-size="14">5</text> <text x="75" y="65" text-anchor="middle" font-size="14">5</text> <text x="105" y="65" text-anchor="middle" font-size="14">4</text> <text x="135" y="65" text-anchor="middle" font-size="14">4</text> <text x="45" y="85" text-anchor="middle" font-size="14">6</text> <text x="75" y="85" text-anchor="middle" font-size="14">7</text> <text x="105" y="85" text-anchor="middle" font-size="14">3</text> <text x="135" y="85" text-anchor="middle" font-size="14">2</text> </svg>
Answer: C
Solution: Key idea: This is a systematic counting question on a matrix, recognisable because it provides a grid of numerical values and asks for the count of cells satisfying a specific inequality condition.
Step 1: Identify the condition. We need to count cells where the pixel intensity U \leq 4.
Step 2: Examine each row systematically.
- Row 1: 0, 1, 0, 2 (All 4 values are \leq 4) -> Count = 4
- Row 2: 4, 7, 3, 3 (4, 3, 3 are \leq 4) -> Count = 3
- Row 3: 5, 5, 4, 4 (4, 4 are \leq 4) -> Count = 2
- Row 4: 6, 7, 3, 2 (3, 2 are \leq 4) -> Count = 2
Step 3: Sum the counts. Total = 4 + 3 + 2 + 2 = 11.
Answer: C
Q4. (CAT 2024) The sum of the following infinite series is<br/>\[2 + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{8} + \frac{1}{9} + \frac{1}{16} + \frac{1}{27} + \cdots\]
Answer: B
Solution: Insight: The series is a mix of a constant, a geometric series with ratio 1/2, and another with ratio 1/3.
Exam route: Group the terms by their denominators' patterns. Sum the two infinite geometric series separately using $S = a/(1-r)$ and add to the initial constant.
Learning route:
The given series is $2 + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{8} + \frac{1}{9} + \frac{1}{16} + \frac{1}{27} + \dots$
Observe the denominators after the first term: 2, 4, 8, 16... are powers of 2. 3, 9, 27... are powers of 3.
We can split the series into three parts:
$S = 2 + \left( \frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \dots \right) + \left( \frac{1}{3} + \frac{1}{9} + \frac{1}{27} + \dots \right)$
The first bracket is a geometric series with $a = 1/2$ and $r = 1/2$. Its sum is $\frac{1/2}{1 - 1/2} = 1$.
The second bracket is a geometric series with $a = 1/3$ and $r = 1/3$. Its sum is $\frac{1/3}{1 - 1/3} = \frac{1/3}{2/3} = 1/2$.
Total sum $S = 2 + 1 + 1/2 = 3.5 = 7/2$.
Correct option is B.
Q5. (CAT 2026) The product of the digits of a three-digit number is 70. The sum of the digits of this three-digit number is _____
Answer: B
Solution: Insight: The product of three single digits is 70, so factorise 70 into three single-digit factors first; the sum follows immediately.
Exam route: $70 = 2 \times 5 \times 7$. These are the only three single-digit factors (any other factorisation like $1 \times 7 \times 10$ uses a non-digit). Sum $= 2 + 5 + 7 = 14$.
Learning route:
Step 1: Prime factorise $70 = 2 \times 5 \times 7$.
Step 2: We need three single digits $a, b, c \in \{1, 2, \dots, 9\}$ such that $a \times b \times c = 70$.
Step 3: Since $70 = 2 \times 5 \times 7$, and all three are single digits, the only valid triple is $\{2, 5, 7\}$. Any attempt to introduce a 1 (e.g. $1 \times 5 \times 14$) forces a factor $\geq 10$, which is not a digit.
Step 4: Sum $= 2 + 5 + 7 = 14$.
Trap: Using $1 \times 7 \times 10$ gives sum 18, but 10 is not a single digit.
Verification: $2 \times 5 \times 7 = 70$ ✓, and $2 + 5 + 7 = 14$ ✓.
Q1. (CAT 2026) Consider the given Python program.<br/> <br/> def fun(L, i=0):<br/> if i >= len(L)-1:<br/> return 0<br/> if L[i] > L[i+1]:<br/> L[i+1], L[i] = L[i], L[i+1]<br/> return 1+fun(L, i+1)<br/> else:<br/> return fun(L, i+1)<br/> <br/> data = [5, 3, 4, 1, 2]<br/> count = 0<br/> for _ in range(len(data)):<br/> count += fun(data)<br/> print(count)<br/> <br/> The output of the program is __________ . (Answer in integer)
Answer: 8.00
Solution: Insight: The inner function `fun` performs one left-to-right pass of adjacent swaps, returning the number of swaps. The outer loop calls it `n` times, which is exactly the Bubble Sort algorithm. The total number of swaps in Bubble Sort equals the number of inversions in the initial array.
Exam route: Count the inversions in `[5, 3, 4, 1, 2]`. 5 is greater than 3, 4, 1, 2 (4 inversions). 3 is greater than 1, 2 (2 inversions). 4 is greater than 1, 2 (2 inversions). Total = 4 + 2 + 2 = 8.
Learning route:
Pass 1: `[5, 3, 4, 1, 2]` -> 5 bubbles to the end. Swaps: (5,3), (5,4), (5,1), (5,2). Count = 4. Array: `[3, 4, 1, 2, 5]`.
Pass 2: `[3, 4, 1, 2, 5]` -> 4 bubbles to index 3. Swaps: (4,1), (4,2). Count = 2. Array: `[3, 1, 2, 4, 5]`.
Pass 3: `[3, 1, 2, 4, 5]` -> 3 bubbles to index 2. Swaps: (3,1), (3,2). Count = 2. Array: `[1, 2, 3, 4, 5]`.
Pass 4 & 5: Already sorted, 0 swaps.
Total count = 4 + 2 + 2 + 0 + 0 = 8.
Q2. (CAT 2024) Consider the following Python function:<br/>def fun(D, s1, s2):<br/> if s1 < s2:<br/> D[s1], D[s2] = D[s2], D[s1]<br/> fun(D, s1+1, s2-1)<br/>What does this Python function fun() do? Select the ONE appropriate option <br/>below.
Answer: C
Solution: Insight: The function swaps the elements at `s1` and `s2`, then recursively calls itself with `s1+1` and `s2-1`. This is the standard two-pointer recursive reversal pattern.
Exam route: Recognize the two pointers moving inwards (`s1+1`, `s2-1`) and swapping elements. This reverses the subarray from `s1` to `s2`.
Learning route:
Base case: `s1 < s2` is false (i.e., `s1 >= s2`), it stops.
Recursive step: swaps `D[s1]` and `D[s2]`, then moves pointers inward.
This exactly reverses the segment `D[s1...s2]` in place.
Q3. (CAT 2024) Match the items in Column 1 with the items in Column 2 in the following table:<br/><br/><table><tr><td>Column 1</td><td>Column 2</td></tr><tr><td>(p) First In First Out</td><td>(i) Stacks</td></tr><tr><td>(q) Lookup Operation</td><td>(ii) Queues</td></tr><tr><td>(r) Last In First Out</td><td>(iii) Hash Tables</td></tr></table>
Answer: A
Solution: Key idea: This is an ADT property matching question, recognizable because it asks to pair fundamental access patterns (FIFO, LIFO, Lookup) with their corresponding data structures.
Step 1: Analyze "First In First Out" (p). This is the defining property of a Queue, where the first element added is the first to be removed. So, (p) matches with (ii).
Step 2: Analyze "Last In First Out" (r). This is the defining property of a Stack, where the most recently added element is the first to be removed. So, (r) matches with (i).
Step 3: Analyze "Lookup Operation" (q). Hash Tables are specifically designed to provide fast, average-case $O(1)$ key-based lookup operations. So, (q) matches with (iii).
Step 4: Combine the matches: (p) - (ii), (q) - (iii), (r) - (i).
Answer: Option A
Q4. (CAT 2024) Consider sorting the following array of integers in ascending order using an in-place <br/>Quicksort algorithm that uses the last element as the pivot.<br/>\[60 \quad 70 \quad 80 \quad 90 \quad 100\]<br/>The minimum number of swaps performed during this Quicksort is ______.
Answer: 15
Solution: Key idea: This is a Quicksort trace problem, recognizable by the request to count the exact number of swaps for a specific array and pivot choice. We must simulate the standard Lomuto partition scheme.
Step 1: Identify the partition scheme.
The problem specifies an "in-place Quicksort algorithm that uses the last element as the pivot". This corresponds to the standard Lomuto partition scheme.
Step 2: Trace the first partition on the array $[60, 70, 80, 90, 100]$.
- Pivot $x = 100$.
- Initialize $i = p - 1 = -1$.
- Loop $j$ from $0$ to $3$:
- $j=0$: $A[0]=60 \le 100$. Increment $i$ to $0$. Swap $A[0]$ with $A[0]$. (1 swap)
- $j=1$: $A[1]=70 \le 100$. Increment $i$ to $1$. Swap $A[1]$ with $A[1]$. (1 swap)
- $j=2$: $A[2]=80 \le 100$. Increment $i$ to $2$. Swap $A[2]$ with $A[2]$. (1 swap)
- $j=3$: $A[3]=90 \le 100$. Increment $i$ to $3$. Swap $A[3]$ with $A[3]$. (1 swap)
- End of loop. Swap $A[i+1]$ with $A[r]$, which is Swap $A[4]$ with $A[4]$. (1 swap)
Total swaps in this step = $5$.
Step 3: Analyze the recursive calls.
The pivot $100$ is now in its correct final position. The left subarray is $[60, 70, 80, 90]$ (size 4), and the right subarray is empty.
Step 4: Repeat the process for the remaining subarrays.
- For size 4 ($[60, 70, 80, 90]$), pivot is $90$. By the same logic, it requires $4$ swaps.
- For size 3 ($[60, 70, 80]$), pivot is $80$. Requires $3$ swaps.
- For size 2 ($[60, 70]$), pivot is $70$. Requires $2$ swaps.
- For size 1 ($[60]$), pivot is $60$. Requires $1$ swap.
Step 5: Calculate the total number of swaps.
Total swaps = $5 + 4 + 3 + 2 + 1 = 15$.
Answer: 15
Q5. (CAT 2024) Consider the directed acyclic graph (DAG) below: <br/><svg width="320" height="300" viewBox="0 0 320 300" xmlns="http://www.w3.org/2000/svg"><rect width="320" height="300" fill="white"/><defs><marker id="arrow-q51" markerWidth="10" markerHeight="10" refX="8" refY="5" orient="auto"><path d="M0,0 L10,5 L0,10 Z" fill="black"/></marker></defs><g stroke="black" stroke-width="4" fill="white"><circle cx="95" cy="45" r="22"/><circle cx="225" cy="45" r="22"/><circle cx="160" cy="112" r="22"/><circle cx="95" cy="200" r="22"/><circle cx="225" cy="200" r="22"/><circle cx="95" cy="265" r="22"/><circle cx="225" cy="265" r="22"/></g><g stroke="black" stroke-width="4" fill="none" marker-end="url(#arrow-q51)"><line x1="105" y1="66" x2="146" y2="94"/><line x1="215" y1="66" x2="174" y2="94"/><line x1="145" y1="132" x2="109" y2="180"/><line x1="175" y1="132" x2="211" y2="180"/><line x1="95" y1="222" x2="95" y2="242"/><line x1="225" y1="222" x2="225" y2="242"/></g><g font-family="Arial" font-size="22" text-anchor="middle" dominant-baseline="middle"><text x="95" y="45">P</text><text x="225" y="45">R</text><text x="160" y="112">Q</text><text x="95" y="200">S</text><text x="225" y="200">V</text><text x="95" y="265">U</text><text x="225" y="265">T</text></g></svg><br/>Which of the following is/are valid vertex orderings that can be obtained from a <br/>topological sort of the DAG?
Answer: ["B","D"]
Solution: Insight: A topological sort is valid if and only if for every directed edge $u \to v$, vertex $u$ appears before vertex $v$ in the linear ordering.
Exam route: Extract all directed edges from the graph diagram. Check each given option to see if it violates any of these precedence constraints. Eliminate options with violations.
Learning route:
Step 1: Identify the vertices and directed edges from the SVG diagram.
The edges are: $P \to Q$, $R \to Q$, $Q \to S$, $Q \to V$, $S \to U$, and $V \to T$.
Step 2: List the precedence constraints derived from these edges:
- $P$ must appear before $Q$.
- $R$ must appear before $Q$.
- $Q$ must appear before $S$ and $V$.
- $S$ must appear before $U$.
- $V$ must appear before $T$.
Step 3: Evaluate each option against these constraints.
- Option A ("P Q R S T U V"): $Q$ appears before $R$. This violates the constraint $R \to Q$. Invalid.
- Option B ("P R Q V S U T"): $P, R$ are before $Q$; $Q$ is before $V$ and $S$; $S$ is before $U$; $V$ is before $T$. All constraints are satisfied. Valid.
- Option C ("P Q R S V U T"): $Q$ appears before $R$. This violates the constraint $R \to Q$. Invalid.
- Option D ("P R Q S V T U"): $P, R$ are before $Q$; $Q$ is before $S$ and $V$; $S$ is before $U$; $V$ is before $T$. All constraints are satisfied. Valid.
Step 4: Conclude that options B and D are the valid topological orderings.
Q1. (CAT 2026) Rishi and Swathi are students of Class 5. Pavan and Tanvi are students of Class 4. Rishi and Pavan are boys. Swathi and Tanvi are girls. The four students played a total of three games of chess. The games were played one after another. A player who lost a game did not participate in any more games. It was observed that:<br/> (i) the first game was the only game where two students of the same class played against each other,<br/> (ii) the students of Class 5 won more games than the students of Class 4, and<br/> (iii) the boys won two games and the girls won one game.<br/> The student who did not lose any game is __________.
Answer: D
Solution: Key idea: This is a constraint-based sequencing and elimination question, recognizable by the sequential games, elimination rules, and conditions on wins/classes.
Step 1: Understand the game format. There are 4 students and 3 games. A loser is eliminated. For all 4 students to play, the format must be: Game 1 (A vs B), Game 2 (Winner of G1 vs C), Game 3 (Winner of G2 vs D).
Step 2: Use condition (i). Game 1 is the ONLY game where two students of the same class played. The same-class pairs are (Rishi, Swathi) in Class 5 and (Pavan, Tanvi) in Class 4. Thus, Game 1 must be either (R, S) or (P, T).
Step 3: Test if Game 1 is (P, T). If Class 4 plays each other in G1, Class 4 wins G1. Condition (ii) states Class 5 won more games than Class 4. Since there are 3 games total, Class 5 must win 2 and Class 4 must win exactly 1. This means Class 5 must win G2 and G3. If Class 5 wins G2, the winner is R or S. Then Game 3 would be (R or S) vs the remaining (S or R), which is a same-class game. This violates condition (i). Thus, Game 1 cannot be (P, T).
Step 4: Test if Game 1 is (R, S). Game 1 is R vs S. Class 5 wins G1. To satisfy the quotas (Class 5 wins 2, Class 4 wins 1; Boys win 2, Girls win 1), Rishi (Boy) must win G1. If Swathi won, we would need 2 Boy wins from the remaining games, forcing Class 4 to win 2 games, violating (ii). So Rishi wins G1.
Step 5: Determine Game 2 and 3. Rishi plays Game 2 against Pavan or Tanvi. If Rishi loses G2, the Class 4 student wins, and Class 4 would end up winning 2 games total (violating ii). Thus, Rishi must win G2.
Step 6: Now Rishi has won G1 and G2 (2 Boy wins, 2 Class 5 wins). The quotas for Boys and Class 5 are fully met. Therefore, Game 3 must be won by a Girl from Class 4 to satisfy the remaining quotas (1 Girl win, 1 Class 4 win).
Step 7: Game 3 is Rishi vs Tanvi. Tanvi must win. Since Tanvi won her only game and didn't play before, she never lost any game.
Answer: D
Q2. (CAT 2025) Let \(p\) and \(q\) be any two propositions. Consider the following propositional statements.<br/> \(S_1 : p \rightarrow q, S_2 : \neg p \land q, S_3 : \neg p \lor q, S_4 : \neg p \lor \neg q,\)<br/> where \(\land\) denotes conjunction (AND operation), \(\lor\) denotes disjunction (OR operation), and \(\neg\) denotes negation (NOT operation). Which one of the following options is correct?<br/> (Note: \(\equiv\) denotes logical equivalence)
Answer: A
Solution: Insight: $p \to q$ is logically equivalent to $\neg p \lor q$ by material implication.
Exam route: Recall the material implication law $p \to q \equiv \neg p \lor q$. Compare $S_1 = p \to q$ with $S_3 = \neg p \lor q$. They are identical in meaning.
Learning route:
Step 1: Write out each statement clearly.
$S_1 : p \to q$
$S_2 : \neg p \land q$
$S_3 : \neg p \lor q$
$S_4 : \neg p \lor \neg q$
Step 2: Apply the material implication equivalence to $S_1$.
$p \to q \equiv \neg p \lor q$
Step 3: Compare the result with $S_3$.
$S_1 \equiv \neg p \lor q \equiv S_3$
Step 4: Verify with a truth table to be absolutely sure.
$p$ | $q$ | $S_1$ | $S_3$
T | T | T | T
T | F | F | F
F | T | T | T
F | F | T | T
The columns for $S_1$ and $S_3$ match exactly.
Answer: $S_1 \equiv S_3$, which is option A.
Common trap: Students sometimes confuse $\neg p \lor q$ with $\neg p \land q$ or $\neg p \lor \neg q$. Remember that implication becomes a disjunction ($\lor$), not a conjunction ($\land$).
Q3. (CAT 2026) Assume that a Creative \((C)\) person will Succeed \((S)\) if the person is also Disciplined \((D)\), but will not succeed otherwise. Now, consider the following statements:<br/> <br/> (i) \(C \land S \Leftrightarrow D\)<br/> (ii) \(C \Rightarrow (S \Longleftrightarrow D)\)<br/> (iii) \(C \Leftrightarrow ((D \Rightarrow S) \lor \neg S)\)<br/> <br/> Which of the following options is correct?
Answer: B
Solution: Insight: "A creative person will succeed if disciplined, but not otherwise" means: if creative, then (succeed iff disciplined).
Exam route: Translate the English sentence step by step. "Creative person will succeed if disciplined" gives $C \to (D \to S)$. "But not otherwise" adds $C \to (\neg D \to \neg S)$. Together: $C \to (S \iff D)$. Check which option matches.
Learning route:
Step 1: Parse the sentence structure.
"A Creative (C) person will Succeed (S) if the person is also Disciplined (D), but will not succeed otherwise."
The phrase "but not otherwise" is the key. It means the condition is both necessary and sufficient.
Step 2: Translate the "if" part.
"will succeed if disciplined" $\implies D \to S$ (within the context of being creative).
Step 3: Translate the "but not otherwise" part.
"will not succeed otherwise" $\implies \neg D \to \neg S$ (within the context of being creative).
Step 4: Combine 2 and 3.
$(D \to S) \land (\neg D \to \neg S) \equiv S \iff D$.
Step 5: Apply the context.
The whole rule applies to creative people, so: $C \to (S \iff D)$.
Step 6: Evaluate the given statements.
(i) $C \land S \iff D$: This means $(C \land S) \iff D$, which is not equivalent. For example, if $C = F, D = F$, the original gives $T$ (vacuously), but (i) gives $F \iff F = T$. Wait, let me check $C = F, S = T, D = F$: original gives $T$, (i) gives $(F \land T) \iff F = F \iff F = T$. Let me check $C = F, S = F, D = T$: original gives $T$, (i) gives $(F \land F) \iff T = F \iff T = F$. Not equivalent. So (i) is FALSE.
(ii) $C \to (S \iff D)$: This is exactly what we derived. TRUE.
(iii) $C \iff ((D \to S) \lor \neg S)$: Simplify the right side. $(D \to S) \lor \neg S = (\neg D \lor S) \lor \neg S = \neg D \lor (S \lor \neg S) = \neg D \lor T = T$. So (iii) becomes $C \iff T$, which means $C$ must be true. This is not equivalent to $C \to (S \iff D)$. FALSE.
Answer: Only (ii) is TRUE, which is option B.
Q4. (CAT 2025) Weight of a person can be expressed as a function of their age. The function usually varies from person to person. Suppose this function is identical for two brothers, and it monotonically increases till the age of \(50\) years and then it monotonically decreases. Let \(a_1\) and \(a_2\) (in years) denote the ages of the brothers and \(a_1 < a_2\).<br/> Which one of the following statements is correct about their age on the day when they attain the same weight?
Answer: B
Solution: Key idea: This is a monotonicity-based logical deduction question, recognizable by the function's trend (increasing then decreasing) and the equality of outputs for two different inputs.
Step 1: Understand the function's behavior. The weight function $W(a)$ monotonically increases for $a \le 50$ and monotonically decreases for $a > 50$. This creates a single peak at $a = 50$.
Step 2: Analyze the condition $W(a_1) = W(a_2)$ with $a_1 < a_2$.
Step 3: Evaluate the positions of $a_1$ and $a_2$ relative to the peak.
If both $a_1 < a_2 \le 50$, they lie on the monotonically increasing segment. For a strictly monotonic function, $W(a_1) < W(a_2)$, so they cannot be equal.
If both $50 \le a_1 < a_2$, they lie on the monotonically decreasing segment. Similarly, $W(a_1) > W(a_2)$, so they cannot be equal.
Step 4: The only way for $W(a_1) = W(a_2)$ with $a_1 \neq a_2$ is if one age is on the increasing slope and the other is on the decreasing slope.
Step 5: Since $a_1 < a_2$, it must be that $a_1 < 50$ and $a_2 > 50$.
Step 6: This matches the condition $a_1 < 50 < a_2$.
Answer: B
Q5. (CAT 2024) Let \(x\) and \(y\) be two propositions. Which of the following statements is a tautology<br/>/are tautologies?
Answer: ["B","C","D"]
Solution: Insight: Convert each implication to disjunction form and simplify. A tautology simplifies to $T$.
Exam route: For each option, replace $A \to B$ with $\neg A \lor B$, then simplify using De Morgan's and absorption. If the result is $T$, it's a tautology.
Learning route:
Step 1: Recall $A \to B \equiv \neg A \lor B$.
Step 2: Evaluate option A: $(\neg x \land y) \to (y \to x)$.
$= \neg(\neg x \land y) \lor (\neg y \lor x)$
$= (x \lor \neg y) \lor (\neg y \lor x)$
$= x \lor \neg y$
This is NOT always true (false when $x = F, y = T$). So A is not a tautology.
Step 3: Evaluate option B: $(x \land \neg y) \to (\neg x \to y)$.
$= \neg(x \land \neg y) \lor (x \lor y)$
$= (\neg x \lor y) \lor (x \lor y)$
$= \neg x \lor y \lor x \lor y$
$= (\neg x \lor x) \lor (y \lor y)$
$= T \lor y$
$= T$
This IS a tautology.
Step 4: Evaluate option C: $(\neg x \land y) \to (\neg x \to y)$.
$= \neg(\neg x \land y) \lor (x \lor y)$
$= (x \lor \neg y) \lor (x \lor y)$
$= x \lor \neg y \lor x \lor y$
$= x \lor (\neg y \lor y)$
$= x \lor T$
$= T$
This IS a tautology.
Step 5: Evaluate option D: $(x \land \neg y) \to (y \to x)$.
$= \neg(x \land \neg y) \lor (\neg y \lor x)$
$= (\neg x \lor y) \lor (\neg y \lor x)$
$= (\neg x \lor x) \lor (y \lor \neg y)$
$= T \lor T$
$= T$
This IS a tautology.
Answer: B, C, D are tautologies.
Q1. (CAT 2025) Which of the following statements is/are correct?
Answer: ["B","D"]
Solution: Insight: Orthonormal bases are not unique (any rotation works), but orthonormality strictly guarantees linear independence.
Exam route: Evaluate each option. A is false because we can rotate the standard basis. B is true. C is false because independent vectors need not be orthogonal. D is true because orthonormal vectors are always independent.
Learning route:
1. An orthonormal basis for $\mathbb{R}^n$ requires vectors to be mutually orthogonal and unit length. The standard basis is one, but any rotation of it (e.g., in $\mathbb{R}^2$, using $(\cos \theta, \sin \theta)$ and $(-\sin \theta, \cos \theta)$) is another. Thus, it is not unique (A is false, B is true).
2. For C, consider vectors $(1, 0)$ and $(1, 1)$ in $\mathbb{R}^2$. They are linearly independent, but their dot product is $1 \neq 0$, so they are not orthogonal. Thus, independent vectors are not necessarily orthonormal.
3. For D, let $v_1, \dots, v_k$ be orthonormal. Suppose $\sum c_i v_i = 0$. Taking the dot product with $v_j$ gives $c_j (v_j \cdot v_j) = 0 \implies c_j = 0$. Thus, they are linearly independent.
Q2. (CAT 2025) The sum of the elements in each row of \(A \in \mathbb{R}^{n \times n}\) is \(1\). If \(B = A^3 - 2A^2 + A\), which one of the following statements is correct (for \(x \in \mathbb{R}^n\))?
Answer: C
Solution: Key idea: The row sum condition directly gives an eigenvalue and its eigenvector, which can be evaluated in the matrix polynomial.
Step 1: The statement "sum of the elements in each row of $A$ is $1$" means that if we multiply $A$ by the all-ones column vector $\mathbf{1} = [1, 1, \dots, 1]^T$, the result is $\mathbf{1}$. Thus, $A\mathbf{1} = 1 \cdot \mathbf{1}$.
Step 2: This implies $\lambda = 1$ is an eigenvalue of $A$, and $\mathbf{1}$ is a corresponding non-zero eigenvector.
Step 3: We are given $B = A^3 - 2A^2 + A$. We can factor this polynomial as $B = A(A^2 - 2A + I) = A(A - I)^2$.
Step 4: Evaluate $B\mathbf{1}$. Since $(A - I)\mathbf{1} = A\mathbf{1} - \mathbf{1} = \mathbf{1} - \mathbf{1} = \mathbf{0}$, we have $(A - I)^2\mathbf{1} = (A - I)\mathbf{0} = \mathbf{0}$.
Step 5: Therefore, $B\mathbf{1} = A(A - I)^2\mathbf{1} = A\mathbf{0} = \mathbf{0}$.
Step 6: Since $\mathbf{1}$ is a non-zero vector and $B\mathbf{1} = \mathbf{0}$, the homogeneous system $Bx = 0$ has a non-trivial solution. Any homogeneous system with a non-trivial solution has infinitely many solutions.
Answer: The equation $Bx = 0$ has infinitely many solutions.
Q3. (CAT 2025) Let \(A = I_n + xx^T\), where \(I_n\) is the \(n \times n\) identity matrix and \(x \in \mathbb{R}^n\), \(x^T x = 1\). Which of the following options is/are correct?
The GATE Data Science and Artificial Intelligence (DA) 2027 course is a structured, data-driven preparation path designed for the 100-mark, 65-question computer-based test. Unlike traditional GATE papers, the DA exam features no separate "Engineering Mathematics" section. Instead, Probability, Linear Algebra, and Calculus are examined as core subjects carrying direct sectional weight. Our curriculum enforces a strict mathematical dependency chain, ensuring you master these foundational topics before advancing to complex Machine Learning and Artificial Intelligence modules.
Built specifically for the fourth edition of this paper, the course is fully mapped to the analysis of 195 previous year questions. You will prioritize high-yield areas like Probability and Statistics (17.95% weightage), Programming, Data Structures, and Algorithms (15.9%), and Machine Learning (13.33%). Furthermore, this program is explicitly designed to break the CS monopoly. Whether you come from an Engineering, Science, Commerce, Arts, or Humanities background, the modules build your programming and mathematical skills from scratch, leveraging the exam's highly inclusive eligibility criteria. With dedicated resources for the unique 15-mark General Aptitude and 85-mark Core DA split, you get the exact strategic edge needed to secure a top rank in February 2027.
n/a. GATE DA is a national-level entrance examination, not a degree program with a fixed duration.
n/a. Intake capacity varies entirely by the specific admitting institute (e.g., IITs, NITs, IISc) or PSU, not the exam itself.
n/a. Salary packages depend entirely on the specific M.Tech, Ph.D., or PSU program a candidate secures admission to via their GATE score, not the exam itself.
n/a. GATE DA is an entrance exam used for admission to various postgraduate (M.Tech, Ph.D.) programs or PSU recruitment, not a degree itself.
Verified, GATE-DA-specific placement statistics are not yet publicly available: the first DA-admitted M.Tech cohorts (which joined programmes like IIT Madras's WSAI in mid-2024) are only now completing a standard two-year programme, so department-level placement reports for this exact pathway haven't been published as of this writing. [NEEDS VERIFICATION: GATE DA M.Tech placement statistics by institute and year]
The closest verifiable, comparable data point comes from a related but distinct cohort: IIT Guwahati's Mehta Family School of Data Science and AI, which graduated its first batch - admitted via JEE for the BTech programme, not GATE DA - in 2025, with an officially reported 91% placement rate and recruiters including Google, Microsoft, and Warner Bros Discovery. This is useful as an indicator of strong, established industry demand for graduates of dedicated data-science-and-AI schools in India generally, but should not be read as a GATE DA placement figure, since the admission route, degree level, and student pool are different.
Historical placement trend narratives specific to GATE-DA-driven M.Tech/MS programmes will become available as more institutes' cohorts graduate over the next one to two admission cycles. Until departmental data is published, prospective candidates evaluating placement strength should look at the host department's broader AI/ML research output and existing (JEE-admitted or general-GATE-admitted) placement history as an indirect signal, while treating any specific DA-cohort salary or placement-percentage figure circulating online with caution unless it cites an official institute source.
GATE DA is not a college degree in itself - it is one of 30 subject papers of the Graduate Aptitude Test in Engineering (GATE), a national-level exam jointly conducted by IISc Bangalore and the IITs on behalf of the National Coordination Board-GATE, Ministry of Education. Clearing the DA paper gives you a GATE score, valid for three years, that you use to apply for postgraduate seats - M.Tech, MS (Research), and PhD - in data science, machine learning, and artificial intelligence at IITs, IISc, NITs, IIITs, and other GFTIs.
DA was introduced in 2024, making it one of the newest GATE papers, built specifically to test the mathematics, programming, and machine learning foundations that data science and AI roles demand - distinct from the more classical computer-science theory tested in GATE CS. The paper covers seven core subjects (probability and statistics, linear algebra, calculus and optimisation, programming and data structures, database management, machine learning, and artificial intelligence) plus a General Aptitude section common to all GATE papers.
Academically, it is aimed at final-year and graduated students of engineering, science, and related disciplines - not only computer science graduates - who want to move into data-science-and-AI-focused postgraduate research or, increasingly, PSU and industry recruitment. GATE 2027, the exam cycle currently open for registration, is being organised by IIT Madras and will be held across six days in February 2027. On MastersUp, "this course" refers to the structured, adaptive GATE DA preparation track - verified notes, topic-wise practice, and mock tests aligned to the current DA syllabus - not a university programme; the actual degree is awarded by whichever institute admits you after the exam.
GATE DA follows the same overall GATE framework as every other paper - computer-based test, GOAPS registration, common result window - but several details are specific to this paper. Unlike GATE CS, EC, or ME, DA has no separate "Engineering Mathematics" section; probability, linear algebra, and calculus are examined as core DA subjects in their own right, which means they carry direct sectional weight rather than being a smaller bolt-on section.
Because DA was introduced only in 2024, GATE 2027 will be its fourth edition, so the previous-year-question pool (2024, 2025, and 2026 papers) is thinner than for legacy papers like CS or ME that have decades of archives - worth building into any preparation plan for this specific paper. DA is also not tied to a single feeder branch: candidates from CS, electronics, electrical, mathematics, statistics, and even non-engineering science backgrounds sit the paper, provided they build the required programming and ML foundations, unlike papers tied more tightly to one engineering discipline.
At the admission stage, DA has an unusual eligibility pattern: some flagship programmes - notably IIT Madras's M.Tech in Data Science and AI at the Wadhwani School of Data Science and AI (WSAI) - accept only a valid GATE DA score and no other GATE paper for that specific seat. Other departments, such as IIT Hyderabad's Department of Artificial Intelligence, treat DA as one of several eligible papers (alongside CS, EC, EE) rather than the sole route in. This means the "one national cutoff opens every door" pattern common to older papers doesn't fully apply to DA - which programmes accept it, and whether it's the only accepted paper or one of several, varies by department and needs checking on each institute's own admission page before finalising a target list.
GATE DA is a 3-hour computer-based test (CBT) worth 100 total marks across 65 questions, split into General Aptitude (15 marks) and the core Data Science and Artificial Intelligence section (85 marks). The exam is held in either a forenoon (9:30 AM-12:30 PM) or afternoon (2:30 PM-5:30 PM) session, with GATE 2027's DA paper scheduled within the exam's six-day window in February 2027, and the specific session/date assigned per candidate.
Three question types appear throughout: MCQ (single correct answer, with negative marking), MSQ (one or more correct answers, no negative marking, no partial credit), and NAT (typed numeric answer, no negative marking). Questions carry either 1 or 2 marks each. The negative-marking rule applies only to MCQs: −1/3 mark for a wrong 1-mark MCQ and −2/3 mark for a wrong 2-mark MCQ; MSQ and NAT questions never lose marks for a wrong attempt, only gain nothing.
One pattern detail specific to DA versus several older GATE papers: there is no separate Engineering Mathematics section, so probability, linear algebra, and calculus are tested as core DA subjects with direct sectional weight rather than as a smaller standalone block. Scores are converted to a normalised GATE score (out of 1000) that adjusts for difficulty variation across sessions, using a formula published in the official GATE Information Brochure each year - always refer to that year's brochure for the exact normalisation method and any pattern updates, such as GATE 2027's additional verification steps (live facial verification, DigiLocker document integration) introduced at the registration stage rather than in the exam pattern itself.
Preparing for GATE DA builds a specific, named skill set rather than vague "analytical thinking." On the mathematics side: probability distributions and statistical inference (hypothesis testing, estimation), linear algebra used directly in ML (eigenvalues/eigenvectors, singular value decomposition, vector spaces, matrix decompositions underlying PCA and SVMs), and calculus-based optimisation (gradient descent, convex optimisation, Lagrange multipliers).
On the computing side: Python programming, core data structures and algorithms (arrays, trees, graphs, sorting/searching, complexity analysis), and database management and warehousing (SQL, normalisation, schema design, OLAP concepts).
On machine learning and AI specifically: supervised methods (linear/logistic regression, decision trees, SVMs, ensemble methods), unsupervised methods (clustering, dimensionality reduction), neural network and deep learning fundamentals, and core AI techniques - informed and uninformed search, adversarial search, propositional and predicate logic, and reasoning under uncertainty (conditional independence, exact inference via variable elimination, approximate inference via sampling).
These are the same building blocks used in real data science and applied-AI roles, which is why GATE DA preparation is often described as dual-purpose: it builds exam-ready recall of formulas and algorithms and, when paired with implementation practice rather than pure theory, functional competence in the tools (Python, SQL, ML libraries) that DS/AI teams actually use day to day.
Getting from "GATE DA aspirant" to "enrolled in an M.Tech/MS/PhD seat" runs through several stages. First, registration on GOAPS (the GATE Online Application Processing System) during the window set by that year's organising institute - for GATE 2027 (IIT Madras), GOAPS opens 27 August 2026, with the regular deadline on 27 September 2026 and an extended, late-fee window until 5 October 2026. Second, the computer-based exam itself, held across designated February weekends. Third, results and scorecards, released roughly a month later, along with the category-wise qualifying cutoffs for each paper, including DA.
From there, the process splits by target institute. For IITs, qualified candidates apply through COAP (Common Offer Acceptance Portal) once individual departments open their DA-based M.Tech/MS admissions and publish their own - usually higher - admission cutoffs or shortlisting thresholds. For NITs, IIITs, and GFTIs, the CCMT (Centralised Counselling for M.Tech/M.Arch/M.Plan) portal handles seat allocation. Some departments layer on an extra stage specific to their programme: IIT Hyderabad's AI department, for instance, shortlists by GATE score and/or academic background and may then call candidates for a written test and/or interview before a final offer; IIT Madras Zanzibar runs its own separate M.Tech screening test rather than relying purely on GATE DA scores.
Once shortlisted or allotted a seat, candidates go through document verification (degree certificates, category certificates where applicable, GATE scorecard), fee payment, and registration at the admitting institute. Because DA-specific seats are still relatively few compared to legacy papers, and acceptance rules differ department by department, checking each target institute's current DA-admission notice - rather than assuming one unified GATE admission process - is a necessary step for this particular paper.
GATE DA rewards a sequenced approach because its subjects build on each other: the mathematics sections are prerequisites for machine learning, and machine learning is consistently among the heaviest-weighted subjects in the paper.
Step 1 - Foundational mathematics first: Start with linear algebra (vector spaces, eigenvalues, SVD, matrix decompositions) and probability & statistics (distributions, estimation, hypothesis testing) before touching machine learning, since ML topics like PCA, SVM, and neural-network backpropagation are built directly on these. Calculus and optimisation (gradients, convexity, Lagrange multipliers) belongs in this same early phase.
Step 2 - Programming and DSA in parallel: Python, data structures, and algorithms don't depend on the math track, so run them alongside Step 1 rather than sequentially - daily, shorter practice sessions here tend to beat occasional long ones.
Step 3 - Machine learning, once the math is stable: With foundations in place, move to supervised and unsupervised ML methods and neural-network basics - this is consistently one of the highest-weighted individual subjects in recent DA papers, so it deserves the largest single block of study time.
Step 4 - The "quick-convert" subjects: Artificial intelligence (search, logic, probabilistic reasoning), database management and warehousing, and any remaining calculus/optimisation topics are comparatively compact syllabi that convert into marks faster once the heavier subjects are under control - good subjects for the middle-to-late preparation phase.
Step 5 - Previous-year questions, subject by subject: After each topic, solve every available GATE DA PYQ on it (2024, 2025, and 2026 papers, since DA doesn't yet have the multi-decade archive that CS or ME candidates draw on) to calibrate what "exam-ready" actually means for that topic, rather than relying on textbook depth alone.
Step 6 - Mock tests and General Aptitude, throughout the final stretch: GA is only 15 marks but comparatively low-effort-per-mark, so don't leave it for the last week. Full-length, timed mocks should start once most of the syllabus is covered and continue weekly through to the exam, with each mock followed by focused error review rather than just a score check.
Step 7 - Revision: In the final three to four weeks, shift from new content to formula sheets, common-mistake logs from mock analysis, and timed sectional drills on your two or three weakest areas.
Indicative time-allocation profiles:
Starting from a non-CS science/engineering background (strong math, little programming): roughly 40% of study time on Python/DSA/DBMS to close the programming gap, 35% on ML/AI, and the remaining 25% split across math revision, GA, and mocks, since the math foundation is usually already stronger for this profile.
Starting from a CS/engineering background with programming experience but light ML/stats theory: roughly 45% on probability, statistics, and machine learning theory, 25% on linear algebra/calculus as applied to ML, 15% on AI, DBMS, and GA, and the remaining 15% on mocks and revision started early.
Repeat attempt or advanced candidate refining an existing score: shift the bulk of remaining time - roughly 60% - into full-length mocks, PYQ-based speed drills, and targeted revision of the two or three topics causing the most lost marks, rather than re-studying the syllabus broadly.
The GATE DA syllabus is structured as eight sections in total: General Aptitude (shared across every GATE paper) plus seven core DA-specific sections - Probability and Statistics; Linear Algebra; Calculus and Optimisation; Programming, Data Structures and Algorithms; Database Management and Warehousing; Machine Learning; and Artificial Intelligence. The full topic-by-topic breakdown within each section is detailed in the subject, unit, and chapter tables on this page - this section explains how the syllabus is shaped and how to sequence studying it, rather than repeating the full topic list.
Structurally, the syllabus has a clear dependency chain: Linear Algebra, Probability and Statistics, and Calculus and Optimisation function as mathematical prerequisites that Machine Learning and, to a lesser extent, Artificial Intelligence build directly on top of - concepts like PCA, SVMs, and neural network training only make sense once the underlying linear algebra and probability are solid. Programming, Data Structures and Algorithms sits somewhat independently and can be studied in parallel with the math track. Database Management and Warehousing is the most self-contained core section, requiring the least dependency on other subjects.
Based on analysis of the GATE DA papers held so far (2024, 2025, 2026 - this being a newer paper without a multi-decade archive), Machine Learning, Programming/DSA, and Probability & Statistics have consistently carried the largest individual shares of the 85 core marks, though GATE does not publish an officially fixed weightage and the exact distribution moves somewhat year to year, so any specific percentage should be read as an informed estimate rather than a guarantee. For the current official topic list, syllabus PDF, and any year-over-year syllabus revisions (GATE 2027 introduced subject-wise syllabus updates across multiple papers), always cross-check against the syllabus document published on that year's official GATE website, since exam-prep summaries - including this one - can lag an official update.

Course CurriculumCourse CurriculumGATE DA itself has no "curriculum" beyond its exam syllabus - the curriculum question really applies to the M.Tech, MS, or PhD programme you're admitted into afterward, and its shape varies by institute. Using IIT Madras's M.Tech in Data Science and AI (Wadhwani School of Data Science and AI, WSAI) as an illustrative example, since it is the flagship programme built specifically around the DA paper: it runs as a standard two-year, four-semester M.Tech, with the first two semesters weighted toward core and foundational coursework - mathematical foundations (probability, linear algebra, optimisation), programming, and core machine learning and deep learning - and the later semesters shifting toward electives, domain-application coursework, and a significant thesis or project component carried out with close faculty supervision, often through WSAI's affiliated research centres. Other DA-accepting departments structure things differently. IIT Hyderabad's Department of Artificial Intelligence, for example, runs multiple admission "modes" (GATE-score-based, high-CGPA-based, and project-experience-based) that feed into the same core-plus-elective-plus-thesis M.Tech shape, but with different screening stages before entry. Programmes at NITs and IIITs generally follow the standard AICTE-aligned two-year M.Tech structure - core subjects in the first year, electives and a project/thesis in the second - though elective menus and thesis expectations differ by department. Across these variations, the general sequencing a DA-driven M.Tech candidate should expect is consistent: foundational and core coursework front-loaded in year one, followed by increasing specialisation, lab or research-group attachment, and a thesis or major project in year two, with the core-versus-elective balance and depth of the research component being the main things to compare when shortlisting between DA-accepting institutes. Because WSAI's M.Tech is unusually GATE-DA-exclusive, its published curriculum is the most directly relevant public reference for DA aspirants planning around "what happens after the exam" - programmes at other institutes should be checked individually before assuming the same core-to-elective ratio applies. Day In LifeA Day in the LifeThere's no single "day in the life" for GATE DA as an exam - a working professional revising in the evenings, a final-year B.Tech student preparing alongside coursework, and a full-time repeat-attempt aspirant all look different day to day. What's common on MastersUp is the shape of the routine, since the platform itself is a fully online, AI-adaptive self-study tool rather than a scheduled classroom programme. A typical weekday for a full-time aspirant might start with two to three hours on a single core subject - say, machine learning or linear algebra - worked through structured, verified notes rather than scattered internet sources, followed by a set of topic-wise practice questions. Because the platform tracks progress and flags weak areas as it goes, the questions served next are meant to concentrate on what a student is actually getting wrong, rather than a fixed worksheet everyone gets. Midday is often spent on programming/DSA practice, since coding problems reward daily repetition more than long single sessions. Evenings tend to shift toward review: revisiting flagged weak topics, attempting a chapter-wise or subject-wise mock, or working through previous-year questions for whichever subject was covered that day. Weekly rhythm typically adds one longer session - a full-length, timed mock test under exam-like conditions - followed by a review pass rather than moving straight to new content, since analysing wrong answers is usually where the biggest score gains come from at this stage. As the exam date approaches (registration for GATE 2027 opens 27 August 2026, with the test itself in February 2027), this rhythm compresses: less new content, more timed sectional practice and revision of a personal "mistakes list" built up over the preceding months. Campus LifeCampus LifeMastersUp is a fully online, AI-powered self-study platform - there is no physical campus, hostel, or classroom attached to GATE DA preparation here, and this page won't claim otherwise about the platform itself. What "campus life" does apply to is the postgraduate programme a candidate joins after clearing the DA paper, and that varies significantly by institute. At IIT Madras's Wadhwani School of Data Science and AI (WSAI) - the department built specifically around this paper - DA-admitted M.Tech students join India's largest dedicated AI department by faculty count (15 full-time faculty at launch in 2024), consolidating existing research infrastructure such as the Robert Bosch Centre for Data Science and AI (RBCDSAI, established 2017), which runs active research in areas including NLP, computer vision, and healthcare AI. Students in this kind of dedicated school typically have access to specialised compute and lab resources, closer faculty-to-student research supervision than in a general department, and a cohort of similarly AI-focused peers across the BTech, MTech, and PhD levels. At other DA-accepting institutes - IIT Hyderabad's AI department, various NITs, and IIITs - campus facilities and the degree of AI-specific specialisation differ, and generic claims about labs, housing, or extracurricular culture at "a GATE DA college" shouldn't be assumed uniformly; these are worth confirming on each institute's own department page once a shortlist exists, since the DA-admission ecosystem is still young and unevenly documented compared to legacy engineering programmes. Alumni StoriesAlumni StoriesGATE DA is young enough - first held in 2024 - that its own M.Tech-admitted cohort (which joined dedicated programmes like WSAI in mid-2024) is only now reaching the end of a standard two-year programme, so verifiable, named alumni placement stories specific to GATE-DA-admitted postgraduate students are not yet publicly documented in detail. [NEEDS VERIFICATION: specific alumni stories for GATE DA-admitted M.Tech/MS cohorts] What is documented, and useful as context for the broader dedicated data-science-and-AI school model that GATE DA feeds into, is the outcome of a related - though not identical - cohort: IIT Guwahati's Mehta Family School of Data Science and AI (launched 2021) graduated its first BTech batch (admitted via JEE, 2021-2025) in 2025, with an officially reported 91% placement rate and recruiters including Google, Microsoft, and Warner Bros Discovery; one graduate went on to further study at Carnegie Mellon University. This is a JEE-admitted undergraduate cohort, not a GATE-DA-admitted postgraduate one, so it should be read as an indicator of strong industry demand for graduates of dedicated AI/DS schools generally - not as a DA-specific placement statistic. Until GATE-DA-specific outcome data is published by individual departments, the more reliable way to gauge likely trajectories is to look at typical patterns rather than individual stories: DA-admitted M.Tech graduates from dedicated schools like WSAI tend to move into applied ML/data-engineering roles, applied-research or R&D positions at technology companies, continue into PhD programmes at the same or a partner institute, or - as GATE DA's acceptance by PSUs and public-sector recruiters matures - pursue government-sector technical roles that increasingly recognise the DA paper alongside longer-established ones like GATE CS. Global ExposureGlobal ExposureInternational exposure tied specifically to GATE DA depends entirely on which postgraduate programme a candidate is admitted into, since the exam itself has no international component. At IIT Madras's Wadhwani School of Data Science and AI - the department most closely tied to this paper - publicly available programme information references DAAD exchange fellowships and other overseas research opportunities available to graduate students, alongside government-funded fellowships for eligible candidates, though exact eligibility, current availability, and application windows for these should be verified directly on WSAI's official site before factoring them into a decision. WSAI's head of department, Prof. Balaraman Ravindran, has international visibility in the AI research community - he has been named among TIME magazine's 100 most influential people in AI and was appointed to the United Nations' Independent International Scientific Panel on AI in 2026 - a reasonable, verifiable signal of the department's research connections, though not itself a guarantee of student-level exchange opportunities. For other DA-accepting institutes, specific international exchange programmes, dual-degree tie-ups, or global faculty collaborations are not consistently documented in public sources at this stage and should be checked department by department. [NEEDS VERIFICATION: global exposure details for GATE DA-accepting institutes beyond WSAI] Course ComparisonCourse ComparisonGATE DA vs GATE CS: Both lead to computer- or data-focused postgraduate seats, but the papers test different things. GATE CS leans on classical computer-science theory - theory of computation, compilers, computer organisation, operating systems - alongside programming and DSA. GATE DA replaces most of that theoretical-CS core with probability, statistics, machine learning, and AI, and has no separate Engineering Mathematics section since the math is embedded directly in its core subjects. Practically, GATE CS is accepted by a far wider, longer-established set of M.Tech CS programmes across almost every IIT/NIT/IIIT, while GATE DA's acceptance is newer and narrower - some flagship programmes like WSAI's M.Tech in Data Science and AI accept only DA and no other paper, while others treat it as one of several eligible options. A candidate aiming specifically at data science, ML, or AI research is better served by DA's directly aligned syllabus; one wanting the widest possible net of eligible M.Tech CS seats is better served by CS's broader acceptance. GATE DA path vs ISI MSQMS / CMI MSDS entrance (both also covered on MastersUp): these are structurally different routes to a similar destination. GATE DA is a single national exam accepted, with varying rules, by many institutes, with no age or attempt limit and a three-year-valid score usable across multiple admission cycles. ISI's MSQMS and CMI's MSDS, by contrast, are admitted through each institute's own dedicated entrance test, leading to a seat at that specific institute only, with a curriculum that tends to be more theoretical-statistics-heavy (ISI in particular) than the applied ML/AI/programming mix GATE DA covers. A candidate wanting flexibility across many institutes and a broader applied AI/ML skill set is usually better served preparing for GATE DA; one set on a specific institute's more mathematically rigorous statistics programme may be better served preparing directly for that institute's own entrance test instead. Quick FactsQuick FactsQ: What does GATE DA stand for? A: GATE DA stands for Data Science and Artificial Intelligence, one of 30 subject papers offered under the Graduate Aptitude Test in Engineering (GATE). Introduced in 2024, it tests mathematics, programming, database management, machine learning, and AI, alongside a common General Aptitude section, for admission to postgraduate data-science-and-AI programmes. Q: Who conducts GATE DA 2027? A: GATE 2027, including the DA paper, is organised by IIT Madras on behalf of IISc Bangalore and the IITs, under the National Coordination Board-GATE, Ministry of Education. The organising institute rotates yearly; IISc Bangalore ran DA's first edition in 2024, followed by IIT Roorkee (2025) and IIT Guwahati (2026). Q: Is there an age limit for GATE DA? A: No. GATE, including the DA paper, has no minimum or maximum age limit, and candidates of any age - students, repeat attempters, or working professionals - can apply as long as they meet the educational eligibility requirement. Q: How many times can I attempt GATE DA? A: There is no cap on attempts. Candidates can appear for GATE DA every year they meet the eligibility criteria, and each attempt produces an independent score valid for three years from the result date. Q: Do I need a computer science background to attempt DA? A: No. GATE DA is open to candidates from engineering, science, mathematics, statistics, and related disciplines, not only CS/IT. Candidates from other branches still need to build the required programming, statistics, and machine-learning foundations themselves. Q: What is the GATE DA exam pattern? A: A 3-hour computer-based test worth 100 marks across 65 questions: 15 marks of General Aptitude and 85 marks of core DA subjects, using MCQ, MSQ, and Numerical Answer Type (NAT) questions, with negative marking applied only to MCQs. Q: How many sections does the GATE DA syllabus have? A: Seven core sections - Probability and Statistics, Linear Algebra, Calculus and Optimisation, Programming/Data Structures/Algorithms, Database Management and Warehousing, Machine Learning, and Artificial Intelligence - plus the General Aptitude section common to every GATE paper. Q: What was the GATE DA qualifying cutoff in recent years? A: The General-category qualifying cutoff has trended downward as the candidate pool has grown: approximately 37.1 in 2024, 29.0 in 2025, and 26.4 in 2026. OBC-NCL/EWS cutoffs are set at about 90% of the General cutoff, and SC/ST/PwD at roughly two-thirds, per the standard GATE category-relaxation rule. Q: Is the qualifying cutoff the same as the admission cutoff? A: No. The qualifying cutoff only secures a valid scorecard; the admission cutoff - the competitive score needed for a seat at a specific institute and programme - is set independently by each department and is typically well above the bare qualifying mark, especially for high-demand, limited-seat programmes. Q: How many candidates appear for GATE DA? A: The candidate pool has grown quickly since 2024: around 39,000 candidates in the first year, rising to roughly 75,900 registered and about 57,000 appearing in 2025, making DA one of GATE's fastest-growing papers. [NEEDS VERIFICATION: exact 2026 and 2027 candidate figures] Q: How long is a GATE score valid? A: A GATE score, including for the DA paper, is valid for three years from the date results are announced, so a single qualifying attempt can be used across more than one admission cycle if needed. Q: Which institutes accept GATE DA scores? A: IIT Madras's Wadhwani School of Data Science and AI requires GATE DA specifically for its M.Tech in Data Science and AI; IIT Hyderabad's AI department accepts DA alongside CS/EC/EE; other IITs, NITs, and IIITs vary in whether and how they accept DA, so checking each target department's current admission notice is essential. Q: What is the GATE 2027 application fee? A: As currently stated for GATE 2027, the application fee is ₹2,000 per paper for General/OBC-NCL/EWS candidates and ₹1,000 for Female/SC/ST/PwD candidates during the regular registration window, plus an additional ₹500 late fee in the extended window - confirm the final figure on the official GOAPS portal when applying. Q: When does GATE 2027 registration open? A: GOAPS registration for GATE 2027 opens on 27 August 2026, with the regular (no late fee) deadline on 27 September 2026 and an extended, late-fee window until 5 October 2026. The exam is scheduled across six days in February 2027. Q: Does GATE DA have a separate Engineering Mathematics section? A: No. Unlike GATE CS or EC, DA does not carry a separate Engineering Mathematics section - probability, linear algebra, and calculus are tested directly as core DA subjects with their own sectional weight. Q: Can I apply for GATE DA and another paper in the same year? A: Yes, GATE allows candidates to apply for up to two papers in the same year, provided the specific combination is permitted by that year's organising institute - check the current GATE brochure for allowed paper combinations. Q: Is there a scholarship for GATE-qualified M.Tech students? A: Many GATE-qualified, full-time M.Tech students (including DA-admitted candidates) are eligible for the MoE/AICTE PG scholarship or an institute assistantship, commonly cited around ₹12,400 per month, though exact eligibility and continuation conditions vary by institute and should be confirmed with the admitting department. Q: Is GATE DA used for PSU recruitment? A: Several established GATE papers are used directly by PSUs for recruitment; because DA is comparatively new, its adoption by individual PSUs for direct recruitment is still developing, and candidates should check individual PSU notifications rather than assume the same pathways as legacy papers apply yet. [NEEDS VERIFICATION: current list of PSUs recruiting via GATE DA specifically] Total AspirantsGATE Data Science and Artificial Intelligence (DA) has experienced rapid growth in aspirant volume since its introduction as a separate paper.
Between 2024 and 2026, total registrations nearly doubled (from ~52,000 to ~91,000), and actual appearances grew from ~39,000 to ~69,000. In 2026, the 69,242 candidates who appeared for the GATE DA paper accounted for approximately 8.7% of the total ~7.97 lakh appearances across all GATE papers, establishing it as one of the most popular and fastest-growing non-traditional streams. Cutoff MarksCutoff MarksGATE DA's qualifying cutoff - the minimum score needed for a valid scorecard, not for admission to a specific programme - has fallen each year since the paper launched, as the candidate pool has grown: from roughly 37.1 (General) in 2024 to 29.0 in 2025 and 26.4 in 2026. Category relaxation follows GATE's standard rule: OBC-NCL/EWS candidates qualify at approximately 90% of the General cutoff, and SC/ST/PwD candidates at roughly two-thirds of it - confirmed by the actual 2025 released figures of 29.0 (General), 26.1 (OBC-NCL/EWS), and 19.3 (SC/ST). Because GATE DA 2027 results aren't out yet, any 2027 cutoff figure is necessarily an estimate based on this multi-year trend, not a confirmed number. GATE DA 2027 Expected Qualifying Cutoff (Indicative, based on 2024-2026 trend)
These indicative figures describe the qualifying threshold only. Competitive, seat-winning scores at high-demand programmes like WSAI's M.Tech in Data Science and AI run well above any of these numbers - see the Cutoff Analysis section for how to think about a genuinely "safe" admission score rather than a bare qualifying one. Rank MarksRank vs Marks AnalysisThe rank a given GATE DA score translates to isn't fixed by any published formula, and because DA is still building its multi-year data history (only three prior editions - 2024, 2025, 2026 - exist as of GATE 2027), a precise, DA-specific marks-to-rank table isn't as reliable as it is for decades-old papers like GATE CS or ME; treat any "marks = rank X" claim seen for DA as a rough estimate rather than a fixed conversion. Directionally, the pattern that holds across GATE papers generally also applies here: the 40-65 mark band tends to be the most densely populated and most rank-sensitive range, where even a 2-3 mark difference can shift rank by a meaningful margin, while very high scores (75+) separate out into a much thinner, lower-competition band typically associated with the strongest institutes and, where applicable, PSU shortlists. Because DA's candidate pool is still smaller and growing year to year, rank-at-a-given-mark is also moving from year to year - a rank that corresponded to a given score in 2025 will not directly translate to 2027 as more candidates enter the paper. [NEEDS VERIFICATION: official GATE DA marks-vs-rank data by year] Eligibility CriteriaEligibility CriteriaGATE DA's eligibility to sit the exam is broad and, on its own, has no age limit and no cap on attempts - a rule common to all GATE papers. Academically, candidates must be currently in the third year or higher of a government-recognised undergraduate degree, or have already completed one, in Engineering, Technology, Architecture, Science, Commerce, Arts, or Humanities; a four-year B.S./B.Sc. (Research) is also accepted. There is no minimum percentage or CGPA required just to appear for the exam, and candidates with backlogs in their qualifying degree can still apply. Unlike some other GATE papers, DA is not restricted to a specific feeder branch such as CS or IT - candidates from mechanical, electrical, physics, mathematics, statistics, or other eligible backgrounds can choose the DA paper, provided they are prepared to build the required programming, statistics, and ML foundations themselves. Both Indian nationals and candidates from a defined set of eligible foreign countries can apply, subject to nationality rules published in the current GATE brochure. Reserved-category candidates (SC/ST/OBC-NCL/EWS/PwD) need valid category or disability certificates in the prescribed format at the appropriate stage of the process; OBC-NCL/EWS certificates are generally required at the counselling/admission stage rather than at GATE registration itself. It's important to separate exam eligibility from admission eligibility: while GATE itself sets no minimum marks to appear, individual institutes commonly require roughly 55-60% marks (or equivalent CGPA) in the qualifying degree at the point of actual M.Tech/MS admission, on top of a competitive GATE score. PlacementPlacement DetailsRoles typically associated with DA-driven M.Tech/MS/PhD graduates from dedicated data-science-and-AI departments include machine learning engineer, data scientist, applied research scientist, AI/ML product roles, and data engineering positions, based on the applied ML, deep learning, statistics, and domain-application curriculum these programmes are built around. Recruiters at comparable dedicated AI/DS schools in the IIT system - drawing on IIT Guwahati's documented first-batch outcomes - have included large technology companies such as Google and Microsoft as well as media/technology firms like Warner Bros Discovery, alongside the broader mix of core-tech and analytics employers that typically recruit from top engineering institutes' placement seasons generally. Company-specific and salary figures tied specifically to GATE-DA-admitted graduates are not yet independently verifiable and are not stated here as confirmed data. [NEEDS VERIFICATION: company-wise and salary-wise placement data for GATE DA-admitted cohorts specifically] Beyond direct campus placement, GATE DA also opens two other outcome paths worth noting: continuation into a PhD at the same or a partner institute, a common trajectory for students in research-heavy dedicated AI schools like WSAI; and, as the DA paper matures and gains wider recognition, potential PSU recruitment routes that currently apply more established to older GATE papers. Candidates weighing placement strength as a factor in choosing between DA-accepting institutes are better served comparing each department's existing (even if not DA-specific) placement track record, faculty research output, and industry partnerships than relying on informal, unsourced salary claims about this specific paper. Course OutcomesCareer OutcomesClearing GATE DA and progressing into a data-science-or-AI-focused M.Tech, MS, or PhD opens several distinct paths rather than one fixed career track. Academically, it's a direct route into research-heavy postgraduate programmes at some of India's newest and most heavily invested-in AI departments - IIT Madras's Wadhwani School of Data Science and AI being the clearest example - with a natural continuation option into PhD study for students who want to stay in research. Industry-facing outcomes, based on the applied curriculum these programmes run (machine learning, deep learning, statistics, and project-based domain applications), typically include roles like machine learning engineer, data scientist, applied research scientist, data engineer, and increasingly generative-AI-focused engineering roles, at technology companies, analytics-driven businesses across sectors, and - as the paper's institutional recognition grows - potentially research labs and PSUs. Because the DA-driven postgraduate ecosystem is still young, longitudinal outcome data - where DA-admitted graduates end up five or ten years out - doesn't exist yet the way it does for older GATE papers. What is reasonably well established instead is the strength of the underlying demand: India's broader dedicated AI/data-science school model (illustrated by IIT Guwahati's 91%-placed first BTech cohort with recruiters like Google and Microsoft) shows real, verified employer appetite for graduates of this kind of specialised programme, even though that specific data point isn't a GATE DA figure. Prospective candidates should read GATE DA's career outcomes as strong and growing, in a genuinely high-demand field, without yet a decade of DA-specific track record to point to.

Unlike GATE CS or EC, there's no separate Engineering Mathematics section; the mathematics is embedded directly within the core subjects. Based on analysis of the 2024-2026 papers (GATE does not publish an official fixed weightage, so this is Indicative rather than guaranteed), Machine Learning and Programming/DSA are consistently among the highest-weighted individual subjects, with Probability and Statistics close behind; combined, the three mathematics-adjacent sections (Probability & Statistics, Linear Algebra, Calculus & Optimisation) typically account for roughly 40% of the core marks, underlining how math-heavy this paper is relative to its "data science" branding. Sequencing matters here specifically because Machine Learning depends on Linear Algebra and Probability being solid first, and because Artificial Intelligence, Database Management, and Calculus are comparatively compact, faster-to-complete sections best slotted into the middle-to-late stretch of a study plan rather than left entirely for the end alongside General Aptitude and full-length mocks. Unit Test KeysTest Series StructureA GATE DA-focused test series is typically layered to match the paper's seven-section structure rather than treated as one undifferentiated question bank. The base layer is unit or chapter-wise tests - short, topic-specific sets (for example, a test purely on eigenvalues/SVD within Linear Algebra, or one purely on decision trees within Machine Learning) meant to confirm a single concept is solid before moving on. The next layer is subject-wise or sectional tests, combining every chapter within one of the seven core sections (or General Aptitude) into a timed set, used once a full section is covered to check retention and speed together rather than just conceptual correctness. The top layer is full-length mock exams, replicating the actual 65-question, 100-mark, 3-hour GATE DA structure across General Aptitude and all seven core sections together, used to build exam-day pacing and stamina once most of the syllabus is covered. MastersUp's GATE track currently includes 65+ mock tests and 15,000+ verified practice questions across this kind of layered structure, spanning the exam's General Aptitude and core DA sections. Question Pattern AnalysisQuestion Pattern AnalysisGATE DA uses three question formats across its 65 questions: Multiple Choice Questions (MCQ, exactly one correct option), Multiple Select Questions (MSQ, one or more correct options, with no partial credit for partially correct selections), and Numerical Answer Type (NAT, a typed numeric value rather than a choice from options). Both 1-mark and 2-mark questions appear across General Aptitude and the core DA section, with 2-mark questions generally testing multi-step or applied problems rather than single-fact recall. The marking scheme, standard across all GATE papers including DA: a wrong MCQ answer costs 1/3 mark on a 1-mark MCQ and 2/3 mark on a 2-mark MCQ; MSQ and NAT questions carry no negative marking at all, though an unattempted question also earns nothing. This makes MSQ and NAT questions comparatively lower-risk to attempt even with partial confidence, while MCQs reward genuine elimination-based reasoning over guessing. Section-wise, the core DA subjects that have carried the heaviest question counts across the 2024-2026 papers are Programming/DSA, Machine Learning, and Probability & Statistics - consistent with their higher indicative weightage discussed elsewhere on this page - while Database Management/Warehousing and Calculus/Optimisation have tended to appear as a smaller, more concentrated set of questions. As with all weightage discussion for this paper, year-to-year question distribution should be read as a planning guide based on past papers rather than a fixed, officially guaranteed pattern, since GATE does not publish a binding per-topic question count in advance. Placement AnalysisLast updated: October 08, 2026 Current Status of GATE DA Placement StatisticsVerified, cohort-specific placement statistics for GATE Data Science and Artificial Intelligence (DA) M.Tech programs are not yet publicly available. The first DA-admitted cohorts, such as those who joined programs like IIT Madras in mid-2024, are only now completing their standard two-year programs. Therefore, official department-level placement reports for this exact pathway have not been published as of this writing. Proxy Indicators for Industry DemandWhile direct GATE DA M.Tech data is pending, the broader industry demand for dedicated data science and AI graduates remains strong. The closest verifiable, comparable data point comes from a related but distinct cohort. IIT Guwahati's Mehta Family School of Data Science and AI graduated its first batch in 2025. This cohort was admitted via JEE for the B.Tech program, not through GATE DA. They reported a 91 percent placement rate with recruiters including Google, Microsoft, and Warner Bros Discovery. This serves as a useful indicator of established industry demand for dedicated data science schools in India, but it must not be read as a GATE DA placement figure, since the admission route, degree level, and student pool are entirely different. How to Evaluate Placement Potential for GATE DASince specific DA-cohort salary or placement-percentage figures are not yet published, prospective candidates must evaluate placement strength using indirect signals. You should look at the host department's broader AI and ML research output and the existing placement history of general GATE-admitted or JEE-admitted students in that same department. What most candidates get wrong hereMany aspirants treat generic average package claims for GATE DA found on coaching websites as fact. Any specific salary figure circulating online should be treated with extreme caution unless it cites an official institute source. GATE DA is a national-level entrance examination, not a degree program. Your salary package depends entirely on the specific M.Tech, Ph.D., or PSU program you secure admission to via your GATE score, not the exam itself. Practical next action: Before applying, download the latest official placement report of the target IIT or NIT department. Check if they have dedicated AI and ML research labs and review the recruiters that visit that specific department, rather than relying on institute-wide aggregate numbers. Key GATE 2027 Timeline

Free Study ResourcesPrepare strategically with our curated resources designed specifically Cutoff AnalysisCutoff AnalysisTwo different numbers get called "GATE DA cutoff," and conflating them is the most common mistake aspirants make. The qualifying cutoff (26.4 General in 2026, trending down from 37.1 in 2024) is simply the bar for getting a valid scorecard - it says nothing about whether that score is competitive for any specific seat. The admission cutoff - set independently by each department, often not published as a single clean number the way the qualifying cutoff is - is what actually determines whether a candidate gets an offer, and for high-demand, limited-seat programmes it typically sits well above the bare qualifying mark. What counts as a "safe score" for GATE DA therefore depends entirely on which programme is being targeted. For a flagship, GATE-DA-exclusive programme like WSAI's M.Tech in Data Science and AI at IIT Madras - where DA is the only accepted paper and seats are limited relative to demand - a safe, competitive score is meaningfully higher than the qualifying threshold; treat any specific number quoted for this as Indicative and confirm against the department's own released admission statistics once available, since DA-specific historical admission-cutoff data is still thin. For departments that accept DA alongside other GATE papers (like IIT Hyderabad's AI department) or for NIT/IIIT-level DS/AI programmes, competitive scores tend to be comparatively more attainable, but are still institute- and year-specific. The trend worth planning around: as DA's candidate pool keeps growing year over year, the qualifying cutoff (likely continuing a gradual downward or stabilising trend as normalisation adjusts for a larger pool) and the admission cutoffs at popular programmes (likely rising, as more well-prepared candidates compete for a still-limited number of dedicated DA-linked seats) are moving in different directions - which is exactly why "clearing the exam" and "getting a preferred seat" are two different targets to prepare for.

It does not have a fixed course duration, intake capacity, or average salary package. These metrics belong entirely to the specific M.Tech, M.S., Ph.D., or PSU program you secure admission to using your GATE score. What most candidates get wrong here is searching for "GATE DA placement stats" as if the exam itself guarantees a salary. Your actual package and intake depend entirely on the admitting institute and the specific program you join. Academically, eligibility to sit for the exam is broad. You must be in the third year or higher of a government recognised undergraduate degree, or have already completed one, in Engineering, Technology, Architecture, Science, Commerce, Arts, or Humanities. A four year B.S. or B.Sc. (Research) is also accepted, with no minimum percentage or CGPA required. Top Institutes and Programs Accepting GATE DA ScoresPremier institutes explicitly accept the GATE DA score for specialized postgraduate admissions. Most institutes do not offer a generic "M.Tech in GATE DA". Instead, candidates use their DA score to apply for specific specializations such as M.Tech in Data Science, M.Tech in Computer Science and Engineering with an AI or ML specialization, or interdisciplinary Artificial Intelligence programs.
Note: The exhaustive list of all NITs, IIITs, and state funded universities accepting the GATE DA score for the 2027 academic session is subject to annual updates in individual institute admission brochures. Navigating Cutoffs, Counselling, and Seat AllocationAdmissions to IITs and IISc using a valid GATE DA score are primarily routed through the Common Offer Acceptance Process (COAP). Meanwhile, NITs, IIITs, and other centrally funded technical institutes use the Centralized Counselling for M.Tech (CCMT). Because GATE DA was introduced only in 2024, the 2027 edition will be its fourth iteration, meaning admission cutoff trends are still stabilizing compared to older papers. Official GATE 2027 Timeline
Your immediate next action should be to review the official eligibility criteria for your target institutes on the COAP portal or the respective CCMT website, as seat matrices and category wise cutoffs fluctuate yearly. Entrance Exam BlogLast updated: October 08, 2026 The GATE Data Science and Artificial Intelligence (DA) 2027 exam is a 3-hour computer-based test worth 100 marks across 65 questions. With no age limit, no cap on attempts, and no minimum percentage requirement, it is designed for candidates in their third year or higher of any recognised undergraduate degree. Since its introduction in 2024, the 2027 cycle marks only the fourth edition, making strategic, data-driven preparation essential. GATE DA Eligibility CriteriaYou are eligible for GATE DA 2027 if you are currently in the third year or higher of a government-recognised undergraduate degree, or have already completed one. This includes Engineering, Technology, Architecture, Science, Commerce, Arts, or Humanities, as well as four-year B.S. or B.Sc. (Research) programs.
GATE DA Exam Pattern and Marking SchemeThe exam is a 3-hour computer-based test scheduled within a six-day window in February 2027. You will be assigned either a forenoon or afternoon session based on official allocation.
Negative Marking RulesNegative marking applies strictly to Multiple Choice Questions (MCQs). You lose 1/3 mark for a wrong 1-mark MCQ and 2/3 mark for a wrong 2-mark MCQ. Multiple Select Questions (MSQs) and Numerical Answer Type (NAT) questions carry zero negative marking. Syllabus Structure and the No Separate Maths RuleThe GATE DA syllabus consists of eight sections: General Aptitude plus seven core DA-specific sections. Unlike GATE CS, EC, or ME, there is no separate Engineering Mathematics section. Probability, linear algebra, and calculus are examined as core DA subjects in their own right. This means they carry direct sectional weight rather than acting as a smaller bolt-on section. Structurally, the syllabus follows a clear dependency chain starting with Linear Algebra and Probability, which form the foundation for Machine Learning and Artificial Intelligence units. Your practical next action today is to download the official GATE 2027 DA syllabus PDF and map its seven core sections against the unit-wise weightage table below. Data-Driven PYQ Weightage (2024 Onwards)Because GATE DA was introduced in 2024, the previous-year question pool is limited to recent papers. Based on an analysis of 195 total PYQs, here is the exact subject-wise and unit-wise weightage you must prioritize. Subject-Wise Weightage

Since it was introduced in 2024, the 2027 cycle is only its fourth edition. To crack it, you need a structured, dependency-respecting study plan that prioritizes high-weightage core subjects over generic rote learning. The Optimal GATE DA Subject SequenceThe optimal subject sequence for GATE DA strictly follows a mathematical dependency chain. You must master Probability, Linear Algebra, and Calculus before attempting Machine Learning or Artificial Intelligence. What most candidates get wrong here is treating mathematics as a separate engineering math bolt-on. In GATE DA, probability and linear algebra are core subjects that carry direct sectional weight. If you jump into supervised learning without understanding random variables or matrix operations, you will struggle with the foundational logic of the algorithms. Your practical next action today is to download the official IIT Madras GATE DA syllabus PDF and map its seven core sections against the unit-wise weightage table before buying any books. Month-by-Month Preparation RoadmapA realistic 6 to 8 month roadmap divides your preparation into four distinct phases, balancing concept building, previous year question practice, and full-length mock tests.

After qualifying the exam, you must register on either COAP for IITs and IISc, or CCMT for NITs and IIITs. Seat allotment relies primarily on your GATE DA score, though MS Research and PhD programs often require an additional written test or interview. Step by Step GATE DA Admission ProcedureThe admission funnel requires you to qualify the exam, register on the correct counselling portal, fill your institute choices, participate in seat allotment rounds, and finally confirm your admission by paying the required fees.
COAP vs CCMT: Understanding the Counselling PortalsYou must choose between COAP for IITs and IISc, and CCMT for NITs, IIITs, and other GFTIs, as these portals manage separate seat matrices and allotment rounds.
For official updates, always refer to the respective portals like ccmt.admissions.nic.in. Interview and Written Test RequirementsWhile M.Tech admissions are largely score based, MS Research and PhD programs almost universally require a written test or interview to assess your subject fundamentals. Institutes use these additional assessments to evaluate your depth of knowledge in areas like Probability, Linear Algebra, and Machine Learning. If you are shortlisted, the interview will focus heavily on your core concepts rather than rote memorization. Admission Pathway for Non Engineering CandidatesCandidates from Science, Commerce, Arts, or Humanities backgrounds can leverage their GATE DA score, but must carefully verify individual institute brochures for specific eligibility criteria or bridge course requirements. What most candidates get wrong hereThey assume a GATE DA score guarantees direct M.Tech admission everywhere. In reality, some institutes restrict non engineering applicants to specific programs or require them to clear an additional departmental test during shortlisting. Your practical next action today is to download the latest admission brochures of your top five target institutes and check their specific degree requirements for GATE DA applicants. GATE DA 2027 Key Admission DatesStay aligned with the official schedule. The exam will be conducted within a six day window in February 2027, followed by counselling in the subsequent months.
Core Subjects vs Elective SpecializationsThe first year universally mandates core subjects that align perfectly with the GATE DA syllabus, ensuring you have the rigorous background needed for advanced topics. Mandatory Core Subjects
Second Year Elective Buckets
Thesis, Capstone, and Project RequirementsYour choice between an M.Tech and an MS Research program dictates your final year workload. M.Tech programs typically culminate in a semester long capstone project or an industry internship, designed to solve applied, real world problems. In contrast, MS Research programs are heavily weighted toward a multi semester thesis. You will be expected to produce original research, often resulting in a publication at a recognized conference or journal. What most candidates get wrong hereThey assume the M.Tech project is just a formality. In reality, top institutes treat the capstone or thesis as a primary hiring signal. Starting your literature review and identifying a faculty mentor by the end of Semester 2 is critical for a strong final output. Your practical next action today is to review the recent thesis titles published by the Data Science departments of your top three target institutes to gauge the expected research depth. Bridge Courses for Non Engineering CandidatesBecause GATE DA welcomes candidates from Science, Commerce, Arts, and Humanities backgrounds, institutes have adapted their curricula to ensure everyone starts on equal footing. Many programs mandate or strongly recommend bridge courses during the first semester. These typically cover foundational programming in Python, discrete mathematics, and basic data structures. This ensures that a candidate with a B.Sc. in Statistics or a B.Com. in Economics can successfully handle the rigorous Machine Learning and Database Systems coursework that follows.

Last updated: October 08, 2026 Cracking the GATE Data Science and Artificial Intelligence exam requires 2.5 to 3 quality hours on weekdays, not unsustainable 16 hour burnout marathons. The 100 mark, 65 question computer based test evaluates your mathematical maturity and Python fluency. Success demands a weightage driven daily routine that prioritizes Probability, Linear Algebra, and Machine Learning over generic coding tutorials. The exam is conducted in two sessions, either forenoon from 9:30 AM to 12:30 PM or afternoon from 2:30 PM to 5:30 PM, within the official window. Whether you are a college student or a working professional, consistency beats intensity. A sustainable weekday schedule allocates specific blocks to prevent cognitive overload. Treating General Aptitude as an afterthought is a critical error. It carries 15 marks. Securing 12 of those marks is often easier than squeezing out 2 extra marks in Machine Learning, yet aspirants skip daily aptitude drills until the final month. Weekends provide 6 to 7 hour blocks for high intensity work. Do not use this time for passive video watching. Your practical next action today is to block out a strict 45 minute window tomorrow morning exclusively for General Aptitude and 90 minutes in the evening for Probability or Linear Algebra. Your weekly study hours must map directly to verified Previous Year Question weightage. The syllabus has a clear dependency chain. Linear Algebra and Probability must precede Machine Learning.
