Hello aspirant,

First of all, your concept should be clear up to 12th standard, so you have to read the NCERT books for basics. After that the following books :-

• R.D Sharma 
• CENGAGE for trigonometry and calculus.
• Arihant publication's previous year questions.

Hope it helps!!!

Hello Aditya,

     I understand your concera and I will help you further !!

         Actually, there are many books innthe market and it is more than enough if you follow one or two books. I think I'm eligible to answer this question. The main thing which decides your rank is your notes which you prepare yourself. The best book for mathematics is R.D.Sharma and no book is very good as per my references during my JEE preparation. Also, you can refer cengage for extra details as well.

Good luck !!
