Hey,

For BAMS course, an OBC category candidate would require 400+ marks for admission in a government college. For semi government colleges, the marks required is atleast 360+ and for private colleges the cut off is low. It's around 280 marks for OBC candidate. 

Now these are just the approximate cut off marks of this year. The actual cut off marks varies from college to college and state to state. You need to score these marks just to be on the safe side.

All the best
