Hello Aspirant

I can guarantee you will score good marks in jee mains chemistry if you study from pradeep’s book . Most of the questions are directly lifted from the book and for proof you can check this year's jee mains question paper. But this is for jee mains chemistry only because I never used pradeep's books for physics and maths.

For jee mains maths : RD Sharma(best book for jee mains)

For physics: BM Sharma (do selective questions because it contains a lot of stuff which is needed for jee advanced)

Hope it helps

Thank you & Good Luck!!!
