how to change my gpat examination centre?

Hi

As asked by you regarding changing the GPAT exam centre, for now there is no scope for the same because NTA has not notified regarding a correction window for GPAT application form . However, November 30 is the last date to register for GPAT 2020, so you can wait if the authorities announce for an option.

Check the following link for any such notification related to GPAT:

Sarita, GPAT has nno correction window. Once you click on the "Submit" button, you cannot make any changes to your application. But if you haven't clicked on the "Submit" button, you can make changes to your application. So, just to answer your question, if you have submitted your application form, you cannot make changes to your application including changing your examination center.
