Hello Susmit , Thanks for asking this question on this platform.if you just want to crack JEE or clear the cutoff then  I will suggest you to solve NCERT maths book and read NCERT physics and NCERT chemistry because these books cover all the syllabus of JEE and if you go through all syllabus then definitely you can score very well in exam .thanks 

Maths :-— NCERT,/R.D. SHARMA/CENAGAE or any other good writer books. Get study material of a national coaching institute and solve it completely. #Resonance or #FIITJEE or #VMC will be better.

Chemistry :— NCERT , For Physical , Inorganic and Organic you can use O.P. TONDON/RC MUKHERJEE, O.P. TONDON and any other good writer book. Solve material completely.

Physics :— NCERT, H.C. VERMA/ D.C. Pandey and then completely solve any coaching material completely.
