Frequently examined in Computer Science and Information Technology: Cache mapping, tag/index/offset, hit ratio and AMAT, C pointer/array/string output prediction, Time complexity of loops, recursion and pseudo-code, Shortest paths, MST and graph algorithms, CPU scheduling calculations, SQL joins, aggregation and nested queries. See the full ranked list with how often each topic appears on the Computer Science and Information Technology subject page.

How to use past papers: Solve the last few years of papers under timed conditions, mark every topic you miss, and revise those first. The pattern above tells you how marks are split across sections.

Frequently asked questions

Where can I download Computer Science and Information Technology previous-year question papers?

Official GATE previous-year papers are published on the official GATE website. Use the official source for authentic papers, then practise with the pattern above.

How many years of Computer Science and Information Technology papers should I solve?

Aim for at least the last 5–10 years of papers. Past papers reveal which topics GATE asks repeatedly and how the marks are distributed.

Should I solve Computer Science and Information Technology sample papers or previous-year papers first?

Start with the latest sample/model paper to learn the current pattern and marking scheme, then move to previous-year papers to see which topics repeat. Finish with full timed attempts to build exam stamina.

What is the best way to use the marking scheme for Computer Science and Information Technology?

After attempting a paper, score yourself against the official marking scheme to see how marks are awarded step-by-step — not just for the final answer. This shows you exactly where you lose marks and how to present answers the way examiners expect.
