Hello aspirant,

No. There's no requirement of 50% marks in each and every subject. Though you're from general category, as per the latest information that the general category candidates in order to be eligible for NEET 2021, need to secure 50% minimum aggregate in 12th whereas SC/ST/OBC category candidates must secure 40% minimum aggregate in 12th boards. So if we calculate the average of three subjects secured by you, then it's coming to be of 52%. So yes, you are eligible for NEET 2021.

Hope, this answer helps you.
