Dear Ranjan,

To apply for JEE Mains, you require many documents.

To apply : these include your class 10th and 12th certificates, a scanned copy of your passport sized photo and signature. If you have applied for category reservation then you will require the category certificate. If you have applied for PWD reservation then a PWD certificate. A residential certificate to certify your address, thumb impression and contact information (email and mobile number).

For exam hall : for the examination hall, you need admit card copy, one passport sized photo and ID proof (such as aadhar, driving license, PAN or voter id card).

To apply for counselling: in addition to these documents you will also need additional documents such as medical certificate, date of birth, admit card of JEE mains, provisional seat allocation number, and payment receipt of seat acceptance fee.

I hope this helps! best of luck!
