is discontinued student again apply for eamcet? is reimbursement is applicable?

Hello,
Yes, you are eligible to appear in AP EAMCET as there is no limit for number of attempts.But the upper age limit is 22 years as on December 31,2020 for General category candidates and for SC/ST the upper age limit is 25 years.Minimum age required is 17 years.
And you will get fee reimbursement if you belong to SC/ST category whose annual income is less that 2.5 lakhs.And for BC, EWS, disabled candidates the annual income limit is one lakh.
So if you fulfill the above eligibility criteria you are eligible.
