Hello aspirant,
With the above mentioned CRL ( general rank) in JEE mains, and looking at the previous year BIT Mesra cutoff, You have very difficult chances of getting any B.tech Branches in BIT Mesra, unless if you are from Home State. So, if you have Home state Quota, then with the above mentioned CRL you can definitely get some decent branches in BIT mesra. But with the All India Quota, you have extremely less chances of getting any branches in BIT mesra.
