For maths,I would recommend to practice the NCERT textbooks of class 11 and 12 but that would not be sufficient.Then you must start practicing problems from Mathematics for class 11 and 12 by R D Sharma to get yourselves familiar with the basic concepts.Then you can go for by Mathematics MCQ by A Das Gupta for JEE mains preparation and Problems Plus in IIT Mathematics by A Das Gupta for JEE advance preparation.

For physics , HC Verma Concepts of Physics,Understanding Physics by D C Pandey (5 books) will be useful for JEE main Preparation and Problems in General Physics by I E Irodov can be used for JEE Advance preparation.

For Chemistry,NCERT books is important for all physical,organic and inorganic.Other than that you can refer P. Bahadur for Problem Practice in Physical Chemistry ,Inorganic chemistry by O.P.Tondon, Organic Chemistry by Morrison Boyd and Himanshu Pandey's Advanced Problems in Organic Chemistry .In addition to this you can also practice questions from New Pattern Chemistry – A master practice book for JEE Main & Advanced R K Gupta.

• Cengage mathematics for Algebra and calculus by G Tewani.
• Mathematics by RD SHARMA ( best for concepts)
• CO-ORDINATE GEOMETRY BY SL LONEY.
• Trigonometry by SL LONEY
• Problems in calculus of one variable by IA MARON
• Lastly, NCERT will always be a good option to take any help of any sort if you find any problem understanding a topic.

• Cengage physics by BM SHARMA ( they are the best books.)
• Resnick and halliday
• HC VERMA
• DC PANDEY for mechanics
• NCERT for all the important theory and concepts needed to build up.

• Inorganic - only NCERT is enough.
• Physical - P Bahadur or RC Mukherjee
• Organic - NCERT and Solomon Frhyle or OP Tandon or Paula Bruice.
