I think it's not possible because now a days competition has increased.OBC category also having good cut off marks But  still stick till the end of the counseling in state to have of chance of getting in mop up rounds of counseling. All the best.

But you can give a try. Don't feel sad. If you can't get the seat then you can take the long term and try again. At that you will get definitely good Mark's. So be confident and try for it.
