I have bought H.C. Verma book both parts 2 years ago. It is very amazing book. Some think that the theory given is conscize. But actually they are not true. Remember it is not a question practise book. Each question has a different concept. It is only a concept building book. Secondly, students should not follow the solutions of this book. The level of questions rise from zero to advance level. Even the beginners can study this book directly. I have not studied this book proprely and now I have not selected in JEE . But now I had started to study this book again from 2 months and noticed the difference. I have mastered in mechanics . I highly recommend to all persons who want to understand physics.
