Vinod, if you belong to OBC Category, the Category you belong to should be also listed in the Central OBC list. Or else you will be considered as General Category and so you have to secure a minimum aggregate of 50% in Physics, Chemistry and Biology. This 50% is inclusive of the Theory and Practical marks scored in Physics, Chemistry and Biology collectively. You needn't score 50% in Physics, 50% in Chemistry and 50% in Biology separately. You need an aggregate of 50% or 40% depending on your Category as an aggregate in Physics, Chemistry and Biology. And along with Physics, Chemistry and Biology, you should also have studied English as one of the core subjects in your 12th. So please check if the Community you belong to falls under Central OBC list or not. If it does, then you are eligible for NEET 2020 by the virtue of scoring 40% aggregate in Physics, Chemistry and Biology. If the Community you belong to doesn't fall under Central OBC list, then unfortunately you will not qualify for NEET 2020 as you will need an aggregate of 50% in Physics, Chemistry and Biology.

Hello Vinod ! Iam glad to inform you that you're eligible for neet exam as the minimum percentage required by a OBC Candidate to appear in neet exam is 40% or above, however in most unlikely cases minimum requirement can be changed, but 25% of total seats are reserved for OBC candidates, so you don't need to worry about that,  Just Work Hard.
