Hey,

The exact cut off marks varies from college to college and it's difficult to predict. Still if you are from the unreserved category, a score of 420+ will keep you on the safe side for BAMS course. If you are from OBC category, 400+ will do. And it's a little lesser for SC/ST categories. These are for government Colleges. For private colleges , the cut off marks are far lesser.

All the best
