As the NCERTs are the best books for the preparation of Jee because these are very helpful to make all the concepts and basics strong and clear and the language of these books is also very easy to understand. So once you are done with these books, you can refer to other standard books as well like -

Physics Concepts of Physics Vol I and II by H.C. Verma Problems in General Physics by I.E. Irodov Fundamentals of Physics by Halliday, Resnick & Walker

Chemistry Numerical Chemistry by P. Bahadur Organic Chemistry by Paula Bruice Yurkanis Inorganic Chemistry by J.D. Lee Organic Chemistry by Morrison & Boyd

Mathematics Maths XI & XII by NCERT Trigonometry by S. L. Loney Co-ordinate Geometry by S. L. Loney Higher Algebra by Hall & Knight Problems in Calculus of One Variable by I.A. Maron.
