Hello aspirant,

One thing you must remember that though you can change your caste category, gender, details of local area you reside, qualification details, mobile number, email-id, special/non special category, you can't change your own name, father's name, date of birth, photo, signature and hall ticket number. Anyways, coming to the point- To change your caste category, you need to click at the official website and go through it. Then give your date of birth, hall entry ticket number, registration number, paying reference details and contact number. Then click " Proceed to fill application" option. There, you will find the way to make changes in the application form and change it. Then take out the printout for future reference after making corrections.

The official website of AP EAMCET 2020 is sche.ap.gov.in/eamcet

Hope, it is helpful.
