For an exam like the NEET (and any other competitive exam for that matter) i suggest you pick 2–3 books and focus completely on them. I suggest you solve each and every question and at the same time make sure your concepts are clear. For anyone writing a competitive exam i suggest you refer to HC Verma’s Concepts of Physics and the NCERT exemplar, you can either download it from the NCERT website, or go out there and buy the book. I also highly recommend solving the additional questions at the end of each chapter in the NCERT text book.
Hope this Helped.
All the Best.
