Hi Shreya,

Yes, it is a problem but not as big as to worry about. NTA has advised you to do so, if you so not do than it's OK, it was just an advice but not a compulsion. As many of the students haven't uploaded their photo with Name and sate if birth on their photo NTA will allow them to appear in the Exam. As per NTA, if a candidate missed uploading a photograph that did not carry name and date, he/she need not worry. The examination authorities will not reject the application form and the candidate will be issued admit card for appearing in JEE Main 2020.
