Hey.

The official website of AP PGECET mentions a list of documents required for counselling. It says that you are required to bring resident certificate or original adhar card, which means that you can bring either of the two. If you have your original adhar card, you do not need to bring the Resident certificate.

You can use the link below to find out more details about the counselling.

Best of luck!
