Graduate Aptitude Test in Engineering — Computer Science 2027

Major PSUs recruiting through GATE CS include ONGC, BHEL, BSNL, DRDO, ISRO, BARC, NIC, and several other central government organisations. Each PSU sets its own GATE score cutoff.

For IIT Bombay CS MTech, you typically need a GATE score above 700 (out of 1000) and rank within top 100-200. IIT Delhi and IIT Madras need similar scores. NIT admission requires ranks within top 1,000-3,000.

The GATE 2027 scorecard is valid for 3 years from the date of announcement of results. This means you can use GATE 2027 scores for admissions and PSU recruitment until 2030.

GATE CS covers: Discrete Mathematics, Linear Algebra, Calculus, Probability, Digital Logic, Computer Organisation, Programming (C), Data Structures, Algorithms, Theory of Computation, Compiler Design, OS, DBMS, Computer Networks, and General Aptitude.

GATE CS is primarily for MTech/PhD admission and PSU recruitment. Top software companies (Google, Amazon, Microsoft) do not require GATE. However, research labs (DRDO, ISRO, TCS Research) value high GATE scores.

General category qualifying marks: 30 (2026), 29.2 (2025) and 27.6 (2024). The cutoff is stable because CS is GATE's largest paper — the μ+σ qualifying formula rarely moves it far. PSU shortlisting and IIT MTech cutoffs are far higher than the qualifying mark.

Begin with the official syllabus — GATE questions rarely go outside it. Then work subject-wise with previous year questions (10+ years), and finish with 8-10 full-length CBT mocks. Remember: General Aptitude (15 marks) and Engineering Mathematics (13 marks) are common to every candidate — 28 of your 100 marks come before the core subject even starts.
