GATE DA Late Fee Deadline Oct 12 & High-ROI Chapter Weightage

The GATE 2027 registration with a late fee is officially open until October 12, 2026. Candidates must complete their application and pay the additional late fee on the official IIT Madras portal, gate2027.iitm.ac.in, before 11:59 PM IST to avoid complete disqualification from the exam. If you are targeting the Data Science and Artificial Intelligence paper, this is your final window to secure your attempt for the February 2027 cycle.

What is the GATE 2027 Late Fee Registration Deadline?

The GATE 2027 registration with a late fee is officially open until October 12, 2026. Candidates must complete their application and pay the additional late fee on the official IIT Madras portal, gate2027.iitm.ac.in, before 11:59 PM IST to avoid complete disqualification from the exam.

IIT Madras serves as the organizing institute for this cycle. The regular registration window has already concluded. This extended period is a strict, non-negotiable deadline designed to give late planners one final opportunity to enter the examination system. Missing this date means you will not receive an admit card, regardless of your preparation level.

Who is Affected by the GATE 2027 Late Fee Window?

This late fee window affects all GATE 2027 aspirants, including those applying for the Data Science and Artificial Intelligence paper, who missed the regular registration deadline. It allows a final opportunity to register, rectify applications, and secure an admit card for the February 2027 exam.

Eligibility for GATE DA remains broad. There is no age limit and no cap on the number of attempts. Academically, you 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. or B.Sc. Research degree is also accepted. There is no minimum percentage or CGPA required to sit for the exam.

A critical detail for DA aspirants is the exam structure. Unlike GATE Computer Science, Electronics, or Mechanical Engineering, the DA paper has no separate Engineering Mathematics section. Probability, linear algebra, and calculus are examined as core Data Science subjects in their own right. This means they carry direct sectional weight rather than being a smaller bolt-on section.

How to Prioritize GATE DA Chapters During Late Registration

With registration closing on October 12, 2026, late registrants must prioritize high-ROI GATE DA chapters. Focus first on Supervised Learning, Random Variables, and Database Systems to maximize your score potential in the limited remaining preparation months.

Based on an analysis of 195 total previous year questions from the 2024, 2025, and 2026 papers, specific units dominate the scoring landscape. Supervised Learning accounts for 21 questions, representing a 10.77 percent weightage. Random Variables follow closely with 20 questions and a 10.26 percent weightage. Database Systems contribute 19 questions, holding a 9.74 percent weightage.

Cold Reality: Most candidates waste weeks on low-yield topics like Spatial Aptitude, which holds only a 3.08 percent weightage, while ignoring the fact that Linear Algebra, Probability, and Calculus are tested as core DA subjects with direct sectional weight, not as a smaller bolt-on section. Master the high-yield chapters first.

At the chapter level, Relational Algebra and SQL Queries alone account for 9 questions and a 4.62 percent weightage. Linear Classifiers and Margin-Based Methods contribute 6 questions with a 3.08 percent weightage. Standard Distributions, including Normal, Exponential, Poisson, and Chi-Square, make up 5 questions and a 2.56 percent weightage.

Structuring your study plan around these verified numbers ensures you cover the most frequently tested concepts first. The GATE DA exam is a 3-hour computer-based test worth 100 total marks across 65 questions. General Aptitude carries 15 marks, while the core Data Science and Artificial Intelligence section carries 85 marks. The exam is held in either a forenoon or afternoon session within a six-day window in February 2027.
