if you really want to crack neet then your main focus should be on ncert textbooks as most of the questions will be asked from it so go through your ncert textbook thoroughly and after that you opt some other books like objective of dinesh,mtg,trueman for biology etc but don't refer too many books opt only one of them and practice as much as you can.i hope this ingormation helps you.

thank you
