Solve 1+ Directed Acyclic Graphs and Topological Ordering previous year questions for GATE DA with answers and detailed solutions. Free sample questions below.
Topological ordering is a way to line up the vertices of a directed acyclic graph so that every directed edge points forward.
Imagine getting dressed: you must put on your socks before your shoes. A topological sort gives you a valid sequence to complete all tasks without violating any prerequisites.

Most platforms hand everyone the same content. Here the content moves with your performance, topic by topic.
Every answer you give moves your topic-level intelligence rate. The next question, the next revision card and tomorrow's plan all change with it.
We only revise topics you have actually attempted and are still below the safe bar on — never the same chapter on repeat.
Each question carries a measured toughness. You are served a rung above your current level, so practice keeps stretching you.
Full lesson cards for first study, curated short-note cards for the last mile — with derivations, traps and exam patterns marked.
Notes, chapter practice, previous-year questions, test series and full-length papers — all feeding one picture of your preparation.
No vanity streaks. Progress here means chapters mastered and accuracy that held up on harder questions.
Full notes and short notes, the complete question bank with worked solutions, mock tests, full-length papers, and an adaptive plan that rebuilds itself as you improve.
