Hi Sharan,

I understand that your OBC certificate has not been accepted by the competent authorities for AIIMS PGI and so to answer your question even a single alphabet on the certificate can make considerable difference and thus in order to get rid of this discrepancy I would like to suggest you to take the original and 2 copies of your caste certificate to a competent authority such as District Magistrate or any group A central government officer for getting yourself issued a new certificate.

BEST WISHES!
