Hey there!

If during the application process you have filled a specific category that is ews, then during the counseling or documents verification, you have to establish the given information with documents. As you are from OBC category, then perhaps you can't get ews certification, in that case, the authorities might deny you admission under the quota.

But if you make the admission criteria without any quota then maybe you could get admission, authority lies with the administration on that regard maybe. Best option will be to contact the respective authority of the examination you have applied in.
