Vipul, NTA will open its correction window from January 15th to January 31st. If NTA notifies you of the changes needed regarding the marks sheet, you can upload the 10th marks sheet. If NTA doesn't notify you of any changes, you cannot make changes to your uploaded images. You cannot change them on your own. But NTA will notify you as it will recognise the error. Please keep an eye on the registered email id and mobile no# for any notifications from NTA.

Hello Mr. Vipul,
It is observed that a NEET application correction is a One Time Opportunity . Once you have made the corrections, no further requests for any other change can be made. The corrections can be made during the scheduled dates fixed by the National Testing Agency (NTA)
