Hii anshu
If you are preparing for NEET then your main focus should remain on ncert textbooks as 85% of questions will asked from that only so first of all go through the ncert thoroughly and after that you can refer any one book for practicing questions like for physics you can refer universal,DC pandey,grb for chemistry you can refer Allen module,mtg,ABC of chemistry and for biology you can refer Truman,objective by dinesh,don't refer too many books as it will confuse you so make sure you refer any one book and practice as much as you can.i hope this information helps you.
Thank you
