Hello Student, 

If we look at JoSAA counselling list of opening and closing ranks then there in no reservation for OBC in BIT.
So,  you would be considered under general category and I am sorry to say that, for that with your score it's not possible to get seat there.

You can apply for some other institutes on basis of your JEE Score,  check here:

Hope this will help.
Feel free to ask any doubts.
