Dear student,

If you are preparing for jee mains, then you must prepare with the best and with the one which is currently updated.

Because now, the competition for jee mains is very much increased and the different varieties of updates question are seen. And for these, old books like hc verma and some board books like Op tandon or p bahadur or rd sharma or rs agarwal will not help you.
Now, as per your query I can assume that you want the maths book name.

So, here is the best book recommendation that will be useful for jee mains as well as jee advanced and by studying this book, definitely you secure a good marks in jee mains as well as in jee advanced

So, for mathematics:-

Use cengage mathematics book series . Solve all the egs, concept application exercise and if you are preparing for jee mains then focus on solving all the single choice correct along with the integer type question ( because the jee mains pattern has been changed ) . Also solve the appendix section that is given at the end of every 4 or 3 chapters.


I hope this helps you and my best wishes are with you for your jee mains exam.
