Have a question related to JEE Main ?

Hello,

Yes, you need an OBC-NCL certificate if you want to claim the OBC-NCL reservation in JEE Main .

Here are the key points:

  • If you want the OBC-NCL quota, you must upload a valid OBC-NCL certificate.

  • The certificate should be issued by the government and must follow the latest format.

  • It should usually be issued on or after 1 April of the current admission year.

Hello,

No, your form will not get rejected because of this.

If the Aadhaar number and personal details match , the photo on your old Aadhaar is not a problem . Many students use Aadhaar with an old photo, and NTA accepts it as long as the details are correct.

Since you have not done final submission yet , you can try once more to edit the Aadhaar number. If the portal still does not allow changes, just continue with the form. It will not cause rejection.

For the exam day, carry:

  • Your updated Aadhaar (new one)

  • The JEE admit card

This is enough. There is no risk of rejection.

Hope it helps !
