Hello,

If you are ISC board students then you have to study more. Because you have to study all NCERT Books for physics, chemistry and botany and zoology. Because in NEET questions are coming from this books mainly. You can study some another MCQ books for chapter wise. You can study yearly MCQ books those are release before the examination. You can study previous year questions also. That's how you will be crack the NEET examination.

All the best.
