Should I focus on boards or NEET during the exams?
During the boards, you can shift your focus from NEET to board exams. Practice subjective and other types of questions asked in the Board exams. Solve sample papers and revise all the chapters. If you feel you have good preparation for Boards, then you can continue with your NEET preparation.
If you are preparing for NEET, the majority of PCB Board topics are already covered. You can study English and the optional subject a few days before the Board exams. With a very rare exception, no student who cracks NEET gets less than 75% in boards if s/he knows the way to write answers.
Hope it helps.
