Yes, you can change the category from General to BCA (Backward Class-A) during the NEET 2024 counseling process, provided you have a valid BCA certificate.

Here’s what you should do:

1. Obtain the Valid Certificate: Ensure you have the official and valid BCA certificate before the counseling process begins.

2. Counseling Registration: During the NEET counseling registration, there is usually an option to update or correct your details, including the category. You can select the BCA category at that stage.

3. Documentation: During the document verification process in counseling, you will need to present your BCA certificate along with other required documents.

If you're unsure about the process or if there are any restrictions, it's advisable to contact the NEET counseling authorities or the respective state medical counseling committee for guidance.
