Dear Sagar

It is going to be a touch and go for you. With 546 rank you may or may not get economics in IIT Roorkie under OBC category. With some 5 to 10 rank lesser, you would have been in a safe zone. But definitely you do stand a chance. Last year the closing rank for Economics in IIT Roorkie under OBC category was 543, which is very near to you.

All the best!
