Hello aspirant,
If you want to get the benefits of ews category then you need to previously enrolled as ews candidate while applying for Eamcet. After the result they may not accept. Once visit your nearest helpline center they will tell you what is what.
Since you are from andhra pradesh, you can avail full fee reimbursement irrespective of your caste category. All you need is a ration card and your annual income must be less than 2.5 lakhs. This scheme is started from the year 2019.
Hope this helps
Good luck
