Greetings aspirant!

Yes SC/ST categories do get some relaxation in minimum required marks in comparison to general and obc categories. But you have to be clear in your question that for which college particularly you want to know SC/ST criteria.

For example in DU Colleges cut-off for SC/ ST candidates are really low. Same is applied in competitive exams as well, some seats are reserved for SC and st candidates which make their minimum required marks really low.

For further doubts feel free to comment down below.
Thankyou!
