Hi

This is very difficult to make prediction that whether you will get  seat or not as  cut off marks for medical colleges keeps changing every year  depending upon various factors like  number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

But when we go through previous data then with 319 marks ,  you hold a chance to get a management quota seat in a private medical college under Tamilnadu State quota

For example,

In Neet 2019, 269 marks for all  categories was the cut off marks to get a management seat in CMC Vellore  under Tamilnadu state quota
