On Question asked by student community
Hello
As an EEE (Electrical and Electronics Engineering) graduate, your core GATE paper is EE (Electrical Engineering).
You can also choose papers like IN (Instrumentation) or EC (Electronics and Communication) if you're comfortable. GATE now allows two-paper combinations EE plus IN is a valid pair.
Choose based on your strengths and future goals (e.g., PSU jobs, M.Tech). Always check the latest GATE brochure for updated paper codes and combinations.
How to clear GATE Exam :
First, know the syllabus and exam pattern.
Make a small study plan and follow it every week.
Read from good books or trusted online notes.
Practice old GATE question papers.
Give mock tests to check speed and accuracy.
Revise your notes and formulas again and again.
How to get Job in PSU:
Score high in GATE, because PSUs take only top ranks.
Keep checking PSU job notices regularly.
Apply on time with your GATE score.
Be ready for interviews or group discussions.
Work on subject knowledge and also your communication skills.
Yes, it will be acceptable. In GATE registration, the name should match your valid photo ID proof in terms of spelling, not the order. Many Indian IDs have surname written first, while the portal generates it as first–middle–last. Since all three parts of your name (Vikash, Rameshbhai, Bhagel) are correct, there won’t be any issue. Just ensure you upload the correct ID proof. During verification, they check spelling, photo, and signature, not the word order.
Hello,
Yes, you can change your category from General to OBC during the GATE 2026 correction window.
GATE always allows candidates to correct details like category. You will need to pay a small correction fee for this change. Make sure you upload a valid OBC certificate as per the format and date mentioned by GATE.
So, wait for the correction window, log in to your application, and update your category to OBC.
Hope it helps !
