Dear aspirant

If you want to be qualified for both jee mains and NEET exam together then you can take PCMB subjects in CBSE board exam and you will be easily eligible for both exam if you score aggregate marks 50% in PCB for NEET and 50% aggregate in PCM for jee mains.

In state board mainly if you choose mathematics as main subject then you can't choose biology as additional subject in many states, if you can do so you can choose like this way in your state board exam and you must pass all of your subject PCMB to seat in both jee mains and NEET. Otherwise you can choose biology as main subject and mathematics as additional subject that's also not issue, whichever subject you get maximum marks that will be your main subject (either biology or mathematics.

So you can choose anyway doesn't matter just three subjects should be there in your marksheet and you have appeared for all three subjects in the same year and got results in same marksheet that's all matters.
