Dear Aspirant,

No book is best for preparing for exam like JEE main, however a combination of two or three good books is more than enough. The first thing that I would suggest is to buy the coaching material of some good coaching like Resonance, Allen, etc. Their material is indeed very good and if you solve it then certainly you can get a good rank. However, if you want to follow a book also then I will recommend Solomons and fryhle.

Hope this helps. Thank you.
