Hello Yalshveer,

A single letter typo in your name on your Aadhar card and caste certificate might cause issues during the admission process at Delhi University, as the university typically requires all documents to be consistent.

Here's what you can do to address the issue:

1. Update Your Aadhar Card and Caste Certificate: You should get the typo corrected as soon as possible. You can update your Aadhar details online or by visiting an Aadhar enrollment center. For the caste certificate, you'll need to contact the issuing authority in your region to get it corrected.

2. Contact Delhi University: If the correction is not possible before the admission process, you should inform the admission authorities at Delhi University about the discrepancy and provide an affidavit stating that the names refer to the same person.

3. Submit an Affidavit: You can also create an affidavit explaining the typo and stating that the documents refer to the same person. This affidavit can be submitted along with your other documents during the admission process.

Addressing this issue early will help prevent potential delays or complications during your admission process.

Hope it helps !
