Hi,

The freeship card issued to ST students is valid for one year from the date of its issue. This scholarship will be offered to students whose family income is not more than INR 2.50 Lakhs during the previous financial year. If the candidate is availing this scholarship then he/she is not allowed to take advantage of any other scholarship offered.

You can check the official notice issued by the government for further details

Hope this helps.
