Hello balakrishnamurthy,

Even though you have not applied  jagan anna vidya deevena scheme. It was not problem you have another option which you have to submit income certificate.

Where your father should be less than 3 lakh.

11) Income certificate of parents from all sources issued on or after 01.01.2017 or White Ration card (candidate name and either of the parents name have to be reflected in the ration card) those who claim tuition fee reimbursement
