You should immediately contact the Karnataka Examination Authority (KEA) to rectify the error in your PGCET application.

The KEA usually provides a window for applicants to correct errors in their application forms.

If you missed this window, you can still try to reach out to them and explain the situation.

Providing incorrect information might lead to complications during the admission process. It's crucial to address this issue as soon as possible.

Be prepared to provide supporting documents like your original mark sheets to validate your claim.

Don't hesitate to contact KEA through their official channels or visit their office directly if necessary
