Hello dear student, 

I think you are not aware of this fact that the motive to conduct neetby nta was to reduce the burden of the students who earlier used to give different entrance examinations for the difference medical colleges. So when NEET came over many of the exams just finished that were taken by the institutions earlier. So CMC Vellore being one of the exam . So now only NEET is the examination you have to give to get into cmc Vellore . I hope this was helpful to you.

Best regards
