Dear aspirant

For getting AIIMS college, your aggregate marks in PCB subject must be 60% in your class 12th board.

You haven't mentioned your category here so I'll be assuming you belong to Gen category.

AIIMS New Delhi cut off rank was 51 for Gen category. As there 21 AIIMS medical College all over India now.

So overall AIIMS college neet cut off marks for different categories after 2nd round of counseling was

Gen -634 marks

EWS -628 marks

OBC - 630 marks

SC -537 marks

St - 509 marks

So if you want to get admission in AIIMS medical College,your marks must be same or greater then last year cut off marks for your better chances.
