Best Books for JEE Main Preparation

The top scorers say that the NCERT textbooks, which the students have studied from at school-level are the most adequate preparation books to ace JEE Main examination. However, the additional reference books are still sought because they have more examples, detailed descriptions of difficult concepts, and most importantly, test questions to put acquired knowledge to practice. Some of the best preparation books for JEE Main 2021 are listed below-

RS Agarwal for Mathematics
RD Sharma's Mathematics Books
Trigonometry and Coordinate Geometry by SL Loney
Concepts of Physics by HC Verma
Problems in General Physics by IE Irodov
OP Tandon's Organic Chemistry
JD Lee's Inorganic Chemistry
Physical Chemistry by P. Bahadur

It is important for candidates to understand how to select the right reference books for JEE Main preparation for themselves.
