What you will find
The question paper for the first of the two Computer Science sessions of GATE 2026 is attached, followed by the official answer key. GATE rotates its organising institute from year to year, so the paper comes from whichever institute hosted that cycle. The key is a short two-page document listing the accepted options, which helps you mark your own attempt quickly.
Working through it
Set aside the full three-hour duration. Attempt the paper in two passes, collecting easy marks first and returning to numerical answer type questions later. Compare with the key and divide mistakes into three groups: theory gaps, silly errors and time pressure.
Topics to expect
- Engineering mathematics, including discrete mathematics and probability.
- Digital logic and computer organisation.
- Data structures, algorithms and programming.
- Operating systems, databases, networks and compiler design.
- General aptitude questions that open the paper.
Who should use it
Final-year engineering students and graduates preparing for GATE or for PSU recruitment through GATE scores. Use it as a recent-pattern check once your syllabus coverage is nearly complete.
Study support
Competer stocks printed engineering and aptitude books that can accompany your paper practice.
Time and marks tips
GATE Computer Science carries questions worth one mark and two marks, and numerical answer questions have no negative marking in the usual scheme while multiple choice items do. Understanding this shapes your risk strategy: attempt numerical questions even when unsure, and guess on multiple choice only after eliminating options. Check the current official information bulletin for the exact marking rules, since they are published each year.
The two-page key helps you tally your marks within minutes.
As a final step, make a one-page record of the paper: the topics that appeared, the marks each carried and the three questions you found hardest. Reviewing such summaries across several years reveals which chapters recur and deserve extra attention in your preparation. Many aspirants find that two or three subjects supply a disproportionate share of marks, and spotting this early lets you plan sensibly.
