The Cut-off depends on various criteria. You cannot just simply predict it. There are 5000 seats that can be allotted under PMSSS. Our country has a reservation policy. Firstly, your 10+2 marks will be preferred, then your Category matters. In simple, if there are 1000 seats for SC/ST/SEBC, then these seats must be filled by 1000 SC/ST/SEBC students even students with only 50% marks will get a seat prior to an open merit general category student.
For General courses, at least more than 65% marks will be needed in class 12th to get into a good college under AICTE Jk scholarship .
