Dear Abhinav, Candidates those have uploaded wrong Photograph, Signature & will be intimated by CBSE through an e-mail & SMS. Candidates will re-upload these documents by log into the application portal in given time frame.

Candidates who will receive the SMS and email from authorities regarding application form correction should re-upload the scanned documents within 3 days.

Dear, 

It is not necessary now. Many have done the same mistake and I guess CBSE has now lifted that criteria. So don't worry dear, this criteria is compulsory for till last years but not now compulsory.. So don't worry about that.. .And study hard. 

Best of luck ! 

Thanks for asking 

As NTA has mentioned proper dimensions for photograph and signature it was necessary to fill up the form accordingly. If you have not applied the NEET as per the specifications, there is no need to worry about it. From January 14 till January 31, you will get a chance to rectify your mistakes. NTA will open a rectification window for the students who have committed mistakes.
