About Graduate Aptitude Test in Engineering — Computer Science (GATE CS) 2027

The Graduate Aptitude Test in Engineering — Computer Science (GATE CS) is one of the most competitive entrance exams, conducted by the IIT Roorkee (2027). Preparing for the GATE CS requires systematic practice, conceptual clarity, and regular self-evaluation. Our platform offers dynamic mock tests, previous years' resolved papers, and AI-enabled analysis to help you secure a top rank.

Frequently Asked Questions

Which PSUs recruit through GATE CS 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.

What is a good GATE CS 2027 score for IITs?

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.

How long is the GATE 2027 scorecard valid?

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.

What subjects are in GATE CS 2027?

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.

Is GATE CS useful if I want to work in software companies?

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.

How to Prepare for GATE CS

1

Algorithms and Data Structures together account for 15-20 marks — master sorting, trees, graphs, and complexity

2

Operating Systems and DBMS are high-scoring — past year questions repeat patterns; solve 10 years of papers

3

Engineering Mathematics (Linear Algebra, Calculus, Probability) contributes 15+ marks — do not skip this section

4

General Aptitude (10 marks) is easy scoring — practice verbal and numerical ability daily for 15 minutes
