Hey there,

Yes, If you belong to OBC Category to prove that you deserve the reservation, caste certificate must be submitted.

To prove that you belong to OBC Category follow the steps:

1. You need to apply for the caste certificate either online or offline.
2. Proof of identity and address are required.
3. Income proof and affidavit of caste are mandatory.

If you failed to submit the caste certificate then you will be considered as an open category candidate and lose your scholarships and other benefits. If you are truly eligible then do not neglect and lose your advantages.

Hope this helps...
