Hello,
If you mistakenly registered as a General category candidate for JEE Mains 2026, but you actually belong to OBC-NCL, you cannot change the category unless the correction window specifically allows category correction. The National Testing Agency (NTA) sometimes provides the option to edit category during the correction window, but this is not guaranteed every year.

If category correction is allowed, you can upload your valid OBC-NCL certificate and update your category. If the correction window does not allow changing the category, then you will have to appear as a General category candidate for that attempt and will not be able to claim OBC-NCL reservation benefits for that session.

Make sure to keep checking the official correction notice to see which fields can be edited.
Hope this helps you.

Hello,
If you mistakenly entered your serial number instead of your admission number during JEE Mains registration, you do not need to worry. NTA mainly verifies your identity through your name, date of birth, school details, photographs, and other documents. The admission number is not used for eligibility verification, so this mistake usually does not cause any issue.
If the correction window opens and allows editing of personal details, you can correct it. If the field is non-editable, you can leave it as it is because it will not affect your exam, admit card, or result. Just make sure all other details are correct.
Hope this helps you.

Hello,

Yes, many IITs now offer specialization BTech programs in AI and data science/engineering, separate from core CSE, while also providing AI/ML/robotics as electives or minors within CSE/other branches, with admission via JEE Advanced, but you'll find specific "robotics engineering" branches more at institutions like IITs/NITs, though IITs integrate robotics in AI/CSE.

I hope it will clear your query!!

Hello,
It is not possible to receive automatic notifications for the forms of JEE Mains SAT and MHT CET. You will need to check the official portals of these exams regularly when the year 2027 approaches. The exam authorities release their application forms through official announcements, and you can stay updated by checking their notices or by following reliable educational sources. You can also set reminders to check updates during the usual application periods so you do not miss any important dates
Hope this helps you.

Hello,

You cannot get automatic notifications unless you personally track the exam websites. However, the best way to stay updated for JEE Mains, SAT, and MHT-CET application form dates is to regularly check their official websites and follow reliable education portals. These exams usually announce forms a few months before the exam.

You can also enable notifications on exam alerts apps or official portals so that you will be informed as soon as the forms are released.

Hope this helps you.
