Hi

In neet 2019 , 470 marks was the cut off marks/ lowest marks that got a government medical college under Tamil Nadu State quota for obc category and it was Government Karur Medical College, Karur

But cut off marks/rank 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.

Also,
this year neet qualifying cut off marks has increased a lot so cut off marks for a seat in medical college is also expected to increase

So ,  you should have at least around  520 marks or more  to be on the safer side in your neet 2020 examination
