For concepts , best books are

HC VERMA physics ,

NCERT chemistry ,

M.L. Khanna Mathematics .

Concepts are very important in iit , when u complete them do revise them again because to apply them u require speed calcuulations which comes only when every concept is in ur heart .

Do approve if u like this

Chemistry:- Organic Chemistry:-O.P.Tondon Physical Chemistry:-O.P.Tondon Inorganic Chemistry:- O.P.Tondon NCERT Text Books -XI & XII classes Organic Chemistry:- Arihant Series Physical Chemistry:- Arihant Series Inorganic Chemistry:- Arihant Series College Chemistry Physics:- Concept of Physics by H.C.Verma Vol.1 Concept of Physics by H.C.Verma Vol.2 Problem in physics-IE Irodov New pattern -Arihant series College Physics University Physics Mathematics:- IIT Mathematics -Tata Mc.Grawhill IIT Mathematics:- M.L.Khanna Objective :-Arihant series Colloge Mathematics

I suggest following books for IIT JEE preparation: Physics MECHANICS Physics by H.C. Verma Problems in physics by I.E.
