If your income is below 1 lakh and you belong to OC caste then you are eligible for reimbursement.
If you belong to backward caste your income level below 2 lacs will fetch you a reimbursement.So be aware of that threshold level that can fetch you fee reimbursement.For scheduled caste people you have separate income level. Every year many lakhs of people write TS EAMCET and many get fee reimbursement.It is not only ts students but also it is applicable for AP students but the sanctioned reimbursement amount is given by AP government for the TS government then you need to apply a separate procedure for the AP government to get your reimbursement if your income is below 1 lakh and you belong to OC caste then you are eligible for reimbursement.

Hope this helps.
