hello sarosh

For covering the syllabus NCERT is best with no other option but in the field of competition after knowledge main thing which will make you winner is PRACTICE . NCERT only cover your syllabus but more and more practice is important so go through some other books for practice .

Some are-

R.D sharma

Tata MacGraw Hill

Arihant publications

Hello sarosh ,thanks for asking this question on this platform.books of class 11-12th math of NCERT cover all the syllabus which will ask in your exam .now when you read the chapter you find that almost all the exercise given in the books are of very easy level so with NCERT please also follow any other good book like -cengage ,Rd sharma etc .thanks

Hello Sarosh,

No, the NCERT is not enough for preparation of WB JEE examination. You should also solve the RD Sharma for Mathematics and solve the previous year question papers, this helps too much and you should also give the mock test to rectify yourself and build your confidence level.

All the best
