go through the ncert text books and there many books which are good individually in every topic

HELLO ASPIRANT!!!!!

This is very difficult to suggest but i will suggest the right one for you because i have gone through the same phase in my life. In my opinion you can prefer RD sharma for problem solving and also for Jee mains.  Please solve the MCQ given in the last and do it sincerely. You can score good rank definitely.

ALL THE BEST FOR YOUR FUTURE!!!!!

Hello student,

For JEE mains, the basic book you need to study is NCERT. Then you have to study some other reference books for some topics in JEE. You may study some books like R.D sharma, S.L loney, Arihant in which you will get better idea for algebra, trigonometry and coordinate geometry.

All the best!
