About Graduate Aptitude Test in Engineering — Electrical Engineering (GATE EE) 2027
The Graduate Aptitude Test in Engineering — Electrical Engineering (GATE EE) is one of the most competitive entrance exams, conducted by the IIT Madras (organising institute for GATE 2027). Preparing for the GATE EE 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 EE 2027?
Power sector PSUs dominate GATE EE recruitment: NTPC, PGCIL, NHPC, THDC, SJVN, CSPDCL, state DISCOMs, and BHEL. NTPC and PGCIL are the most prestigious with excellent salary packages.
What is the NTPC recruitment cutoff for GATE EE?
NTPC Engineer Trainee through GATE EE typically requires scores above 600-650 and ranks within top 300-500. The selection also includes a Group Discussion and Personal Interview round.
What are the most important subjects in GATE EE?
Power Systems, Electrical Machines, Control Systems, and Power Electronics together account for 50-55 marks in GATE EE. These four subjects should be the primary focus of your preparation.
What MTech can I pursue with GATE EE?
GATE EE qualifiers can pursue MTech in Power Systems, Control & Instrumentation, Power Electronics, Electrical Drives, Renewable Energy Systems, and Smart Grid Technology at IITs and NITs.
Is GATE EE accepted by IISc Bangalore?
Yes, IISc Bangalore accepts GATE EE for ME (Research) in Electrical Sciences. The cutoff for IISc is very high — typically top 50-100 ranks. GATE EE is also accepted for IIT Bombay, IIT Delhi, and other IITs.
What is the GATE EE qualifying cutoff?
General category qualifying marks: 27.7 (2026), 25 (2025) and 25.7 (2024). Power-sector PSU shortlists (NTPC, PowerGrid) typically need GATE scores above 650, i.e. 60+ raw marks.
How should I start preparing for this GATE paper?
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.
How to Prepare for GATE EE
Power Systems (Load Flow, Fault Analysis, Protection) and Machines carry highest weightage — start here
Control Systems involves Laplace Transforms and Root Locus — practice numerical problems daily
Circuit Theory fundamentals are tested across multiple subjects — master Thevenin, Norton, and network theorems
Electromagnetic Fields is mathematical — solve previous year questions repeatedly to identify recurring patterns
Electrical Machines and Power Systems contribute 30+ marks together — treat them as one combined syllabus
Practise three-phase and per-unit conversions until they are automatic; they appear in faults, machines and transmission numericals alike
