Hi,

With the marks of 315 in NEET and belonging to the general category , the chances of getting a seat in the government medical colleges is not at all possible. However you may try for private medical colleges also through management quota seats which might be quite possible. The private medical colleges in Tamil Nadu include

Sri Ramachandra Institute of Higher Education and Research, Chennai

Amrita Vishwa Vidyapeetham, Coimbatore

CMC Vellore - Christian Medical College
