Hello
If you're in 2nd year right now, you can’t register for GATE 2026 just yet.
The exam is only open to students in the 3rd year or beyond in their degree.
It’s mainly because the GATE tests subjects that are usually taught later in your course.
But don’t worry, you are in a great position to start preparing early!
Focus on your basics, practice problem-solving, and build strong concepts now.
By the time you reach 3rd year, you’ll be well ahead of the game.
Hello,
If your GATE 2026 application shows "under scrutiny," continue to monitor your applicant portal and registered email for updates, as this is a routine process where officials verify your details. An "under scrutiny" status does not mean your application is rejected; you may be notified of discrepancies and given a chance to correct them during the application correction window, which opens later. Keep your application details accurate and prepare for the exam while waiting for the correction window to open.
I hope it will clear your query!!
Hello,
In the GATE application form , you should enter your name exactly as it appears in your official ID proof , even if the order is different.
For example:
If your ID proof shows Surname + First Name , enter it in the same way in the form.
Do not change the order to First Name + Surname.
This is important because your GATE admit card and scorecard will match your ID proof.
Keep it exactly the same to avoid any issues later.
Hope it helps !
Hello,
Yes, you as a Bachelor of Science graduate in home science can appear for the GATE 2026 exam, as the eligibility criteria include graduates from "Science" and other fields, as well as those in the 3rd year or higher of an undergraduate program.
I hope it will clear your query!!
Hey! The GATE exam (Graduate Aptitude Test in Engineering) is very important for long-term career growth. It opens opportunities for postgraduate studies (M.Tech, MS, PhD) in top institutes like IITs and NITs and is also used by many public sector companies (PSUs) for recruitment, often with higher salary packages. In the long run, qualifying GATE can enhance your technical knowledge, career prospects, and credibility in the engineering field.
