As we know that there is very less time left for NEET exam so if you want to score good marks in NEET then your main focus should remain on NCERT textbooks as most of the questions are asked from it so make sure along with your MTG you should read NCERT textbooks thoroughly.Try to solve one practice paper daily so that you can assess yourself. If you have read your NCERT textbooks then  you can easily score above 500 marks.i hope this information helps you.
