Hello

There are various books through which candidates will be able to prepare for JEE (Main) examination. While NCERT books are usually highly recommended for preparation, there are many other books also. 

To build your concepts, you should refer to NCERT textbooks and use the other reference books for in depth knowledge and understanding of the concepts. 

Some of the important books are:

Physics- Concepts of Physics by H. C. Verma, Fundamentals of Physics by Halliday, Resnick and Walker, Problems in General Physics by I. E. Irodov, Understanding JEE physics series by DC Pandey, University Physics by Freedman and Young

Chemistry- Numerical Chemistry by P. Bahadur, Organic Chemistry by Solomons and Fryhle, Concise Inorgranic by JD Lee, Organic Chemistry by Morrison and Boyd, Arihant's Practice Book Chemistry for JEE Main And Advanced by R.K Gupta

Mathematics- Higher Algebra by Hall and Knight, Coordinate Geometry  by SL Loney, Calculus and Analytic Geometry by Thomas and Finney, Course in Mathematics for IIT-JEE by Tata McGraw Hill publication, Problems Plus in IIT Mathematics by A Das Gupta, Trigonometry by S L Loney.

Speed and accuracy both are the key factors to score a good rank in the exam, you should practice mock tests and analyse your preparation level after every mock test. This will help you alot to enhance your speed, accuracy and you will also get familiar with the exam pattern and will be confident to face the mail exam.

You can enroll for the JEE Main Knockout for an effective preparation of the exam. You'll get smart study material, E lectures, Advanced test Series based on the JEE Main pattern along with performace analysis also.
