Hello Ekta,

To be eligible for NEET, you must have passed your 12th Board with subjects Physics, Chemistry Biology and English as main subjects. Your aggregate PCBE percentage must be 60% minimum , else you will not be eligible to appear for NEET.

Yes, you have to give 12th re-examination from NIOS to get atleast 40% to 42% in Chemistry Subject. Since you have already scored well in Physics and Biology, less marks of Chemistry will work. But you have not mentioned your English marks here.

Look for individual marks of all the 4 Subjects, sum it all and divide it by 400. If you right now only get 60% aggregate then no need to give NIOS. But if not, then start preparing.

This will make your aggregate PCBE percentage of 60% which is needed. Then only, you will be able to apply for NEET.

Here are some tips for NIOS 12th re-examination preparation :-
