No college, including BIT Mesra, admits students on the basis of JEE Mains marks. Rather, admissions are made on the basis of JEE Mains rank. Suppose there are 15 candidates with the same score, their ranks may still differ. If the college has only 10 seats left for that particular course, the top 10 out of those 15 students (having more marks in Maths or Physics) will be given the seats.

There are OBC-NCL and OBC-NCL (PwD) admissions at BIT Mesra through JoSAA counseling. However, 54 seats are offered by BIT Mesra in the OBC category for BC1 and BC2, only to the students of Jharkhand.

The college releases the notification to apply for these seats on its official website. If you are from Jharkhand, you can get a seat at BIT through this allotment scheme, in a branch such as Civil or Chemical. If luck favors you, you may even get into EEE or Mechanical. If you are a non Jharkhand candidate, you can only get in through your general rank in AI quota. Most probably your General AI rank is 80k+. This rank won't be enough to get an admission into BIT.

Thus, your rank won’t possibly get you an admission into BIT Mesra. However, you go for the NIT of your home state.
