My name in adhaar card/bank account is different than my 10th/12th certificate. Adhaar/Bank has shaikh at last. 10th/12th have shaikh in the front. I've taken admission in IGNOU, it doesn't match my adhaar. So i have discrepancy in abc id and adhaar name. Plus I didn't attach my father's name with my name in IGNOU so it doesn't match my 10th/12th board name also. I can get the IGNOU name fixed. I'm getting an affidavit. But is it wiser to change my adhaar name to match my 10th/12th name or should I change my graduation name to match my adhaar name?

Your 10th and 12th certificates have Shaikh at the beginning, but your Aadhaar and bank have it at the end. IGNOU used the Aadhaar name, so your graduation name doesn’t match school records, and even ABC ID isn’t linking.

It's better to match your graduation name with your 10th and 12th, since those are used for most verifications. You can update your Aadhaar later using an affidavit and supporting documents. This will avoid issues in jobs and higher studies.
