About the GATE EC Exam
GATE (Graduate Aptitude Test in Engineering) Electronics and Communication Engineering (EC) is a national-level Computer-Based Test conducted jointly by IISc Bengaluru and seven IITs for admission to M.Tech/M.E./Ph.D. programmes across India and for recruitment by Public Sector Undertakings (PSUs) such as IOCL, BHEL, NTPC, GAIL, BPCL, HPCL, ONGC, PGCIL, and ISRO. GATE 2026 is organised by IIT Guwahati. The EC paper tests 65 questions for 100 marks across General Aptitude (15 marks), Engineering Mathematics (~13 marks), and the seven core ECE subjects: Networks/Signals/Systems, Electronic Devices, Analog Circuits, Digital Circuits, Control Systems, Communications, and Electromagnetics.

Frequently Asked Questions
What is the GATE EC 2026 exam pattern?
GATE EC 2026 is a 3-hour Computer-Based Test with 65 questions worth 100 marks. The paper has 15 marks of General Aptitude (10 questions), about 13 marks of Engineering Mathematics, and 72 marks of EC subject content. Question types are MCQ (with negative marking of −1/3 or −2/3), Multiple Select Questions (MSQ, no negative marking), and Numerical Answer Type (NAT, no negative marking).
Who is conducting GATE 2026 and what is the application fee?
GATE 2026 is organised by IIT Guwahati on behalf of IISc Bengaluru and seven IITs under the National Coordination Board (NCB-GATE), Ministry of Education. The regular application fee is INR 1800 for general candidates and INR 900 for SC/ST/PwD/Female candidates. A late fee of INR 500 applies after the regular deadline. International candidates pay a higher fee in USD.
How is the GATE score calculated and how long is it valid?
The GATE score is computed on a 0-1000 scale using a normalisation formula that accounts for the qualifying mark, the mean and standard deviation of the top 0.1% of candidates, and the candidate's actual marks. The score card is valid for 3 years and is used for PG admission to IITs/IISc/NITs/IIITs and PSU recruitment by IOCL, BHEL, NTPC, GAIL, ONGC, PGCIL, ISRO, and many others.
What topics carry the most weight in GATE EC?
By weight, the largest core subjects are Networks/Signals/Systems and Analog Circuits (~12 marks each), followed by Digital Circuits, Control Systems, and Communications (~10 marks each), Electronic Devices (~10 marks), and Electromagnetics (~8 marks). Engineering Mathematics adds ~13 marks and General Aptitude is fixed at 15 marks across every GATE paper.
Is there negative marking in GATE EC?
Yes, but only on MCQ-type questions. For 1-mark MCQs, a wrong answer carries −1/3 mark. For 2-mark MCQs, a wrong answer carries −2/3 mark. MSQ (Multiple Select Questions) and NAT (Numerical Answer Type) have no negative marking, so it is strategically wise to attempt all of those.
When is GATE 2026 EC scheduled and when do registrations open?
GATE 2026 is scheduled for early February 2026, with EC typically held on a Saturday afternoon session. Registration on the GOAPS portal at gate2026.iitg.ac.in typically opens in late August 2025 and closes in late September with extension via late fee. Admit cards are released in early January 2026. Always check the official notification at gate2026.iitg.ac.in for exact dates.
What is the eligibility for GATE EC?
Eligibility is having completed (or being in the final year of) a Bachelor's degree in Engineering/Technology or equivalent in a relevant branch — typically B.E./B.Tech in Electronics, Electronics and Communication, or related disciplines for the EC paper. There is no upper age limit. Final-year students and those who have completed any government-approved degree may apply.
