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.
