hi! if you are already a first year student of bams and have now cracked neet and want to take admission in mbbs, then you will be required to take your tc and pay the fees for the remaining bams course.

but if you took a bams seat during counselling itself and now want to leave it, then you can do it, but for this too, if the bams councelling procedure has been completed, then you are again to pay the fees for the entire course and then leave the seat. but if the counselling procedure is yet to be completed, then maybe you will be required to pay only the security deposit.

but to be on the safer side, it would benefit you to also contact the concerned authorities.
