Hey,

With 72.2% in 12th Boards you qualify for admission and fulfill the eligibility criteria of the college BIT Mesra, but to get admission in Btech Courses in BIT Mesra you need to clear jee mains with a valid (CRL )AIR rank. If you get a valid score and rank then you can get admission in BIT Mesra.

I hope this helps.

All the best!
