Dear pramod, 

According to me atleast 400+ marks are required for bhms.But there's is no record for such marks as the cut off changes depending on the state and the number if students getting good score each year but to be on the safe side atleast 400+ marks are need 

This is the minimum so ALL THE BEST FOR YOUR COUNSELLING!!
