Hey,

Candidates were asked to submit recent passport size color picture, with your name and date printed on it.

But If you have not uploaded the same, no need to worry. The photograph that you have submitted will be accepted. Else, you will receive a mail from JEE mains conducting authority (Central Board of Secondary Education) somewhere about in March, and you will be asked to make required changes but Just make sure for now that the other details should be correct. The last date to make OTHER changes in application form is January 22, 2018 .

Hope it helps!
