Hello,

The eligibility criteria for NEET 2021 is

• The applying candidates must have passed class 12 or equivalent with Physics, Chemistry, Biology/Biotechnology and English as core subjects from a recognized board.
• Candidates need to have secured minimum 50% marks in aggregate in PCB subjects in class 12. The minimum marks required for SC/ST/OBC candidates are 40%

If you are general candidate then you need to score 150/300 in combining PCB marks in class 12. since,  you have secured more than  minimum required marks so you can give NEET 2021.

But, to get admission in AIIMS you need to fulfill the eligibility criteria of AIIMS. If you are general or OBC candidate then to get admission in AIIMS you need to have minimum 60% marks in aggregate in class 12. But, if you are SC/ST candidate then the minimum marks required will be 50%.

good luck!
