Dear Aspirant,

As per last year's cutoff for OBC category, candidate's who scored marks above 540 were able to get government medical seat through state level quota. According to All India Quota 560 was considered a safe scored to get government medical seat.

Sorry to say but 400 is very low score for an OBC candidate to get government medical seat.With these score you can get good semi government and private college's and there are chances of your's to get government BHMS/BAMS college.

As you have not mentioned your state,so its quite difficult to predict your college.You can use  the given below link to predict your college by submitting your score.
