Sir i have got 63 in physics, 52 in chem and 61 in bio, am I eligible for neet?

Dear Soumya, you haven't mentioned your category. Neverthless, because your aggregate is more than 50% in Physics, Chemistry and Biology, you are eligible to appear in NEET. For General Category candidates it is 50% aggregate that is required in Physics, Chemistry and Biology. It is 45% for PWD and 40% for SC, ST, OBC. But regardless of your Category because you have surpassed 50% aggregate in Physics, Chemistry and Biology, you are eligible for appearing in NEET.
