Hello B. Rahul Dev,

The eligibility criteria for NEET 2021 are as follows:

• The class 12th percentage required for students is 40% for SC/ST/OBC and 50% for general.
• Candidates must have completed 17 years of age as on 13 December 2021.
• Candidates must have completed physics, chemistry and biology/biotechnology and English as core subjects from a recognized board

But uptill AIIMS conducted it's own paper the criteria was a bit different as the minimum aggregate required was 60% for GEN and OBC candidates and 50% for SC/ST candidates.

So you are safe :)
