-NCERT Class XI and XII books. -Concepts of Physics by H. C. Verma. -Fundamentals of Physics by Halliday, Resnick and Walker. -Problems in General Physics by I. E. Irodov. -Aptitude Test problems in Physics by S. Krotov. Chemistry:
-NCERT Class XI and XII books. -Numerical Chemistry by P. Bahadur. -Concise Inorganic Chemistry by J. D. Lee. -Organic Chemistry by Morrison and Boyd. Chemistry Principles & Applications by Slenko and Plane. -University Chemistry by Bruce Mahan for Physical Chemistry. In order to these books you can write number of mock tests, then definitely you can crack. Hope it helps you. !
Best of luck!

Tips for attempting exam
1. Start with your favourite subject. Than second favourite and in the last least favourite.
2. For every question make a decision. You can solve or not. Solve all the questions of paper which you can solve. Leave the tough ones or the ones which you are not sure. Mark those questions which you think you can never solve.
3. While solving leave the question which gets stuck in between. Keep leaving until you find easy Question. JEE Advanced is about solving easy Questions.
4. Now in last 40-50minutes. Try to solve those questions which you think you maybe able to solve. Try them out.
5. Be very careful with integer types. Check calculations and don't rush. If you will attempt paper with more than 90% accuracy. Than even less paper attempt can also give you good Institute.
6. In MCQ even if you are getting some option correct. Still check all options and think if this can be correct. And if it wrong than why it is wrong.

I can guide you about Physics important chapters for JEE Advanced.
1. Oscillations and Waves. (Oscillations more important)
2. Rotational Motion and centre of mass. ( Angular momentum extra)
3. Electrostatics
4. Current electricity
5. Magnetism
If you have done B.Sc. Than your concepts will be better and also your ability to use mathematics in Physics will be more. Start by solving previous year questions of JEE Mains and JEE Advanced. SEE the solutions and solve all questions. Spend atleast 3 months in this. But not more than that. By now you will know your weak and strong area. Give one full reading to standard Physics textbook like sl Arora. Purchase one assignment book like dc pandey series. Solve it completely. Once you start solving this book. Make a habit of giving one test every week. Online test. You can give full JEE test every week even if your syllabus is not complete. Just give test and don't worry about marks. This will help you in managing time in exam. Solve entire assignment book. Now try to look for any gaps. If you feel some topics are weak. Only focus on those. Revise same book more. Than solving too many books. Anf always try to solve question by yourself first and than SEE the solution.

JEE Advanced Physics can be cracked with good percentile using following tips.
1. Keep your resources very limited. Don't use too many books or materials. Complete one JEE Advanced level book I. Detail and Completely.
2. First step is buy JEE Advanced previous year solutions book. Students think this is the last step. But no this is the first step. Make sure your book is divided topic wise with detailed solutions. Many such books are available.
3. Second step is to choose a topic and read it's NCERT Book along with problems of NCERT. There are some books like NCERT Fingertips. After you read Ncert, solve the questions based on ncert chapter. Don't rush and spend some time for this.
4. It is time to level up. But don't level up soo soon. Atleast complete 2-3 chapters of NCERT before level up.
5. Now do previous year solutions of JEE Mains and JEE Advanced of those chapters. Look at the solutions of the questions. Learn the techniques to solve those problems. SEE how solutions is done. Complete all questions. Try to completely understand each and every solution.
6. Now again come back to ncert and do 2-3 more chapters
7. Again do previous year Questions of those chapters.
8. Repeat the process until you complete your class 11 entire
9. Try to complete class 11 in this way in just 6-7 months. Remember do only these steps. No tests, no assignments, no extra books.
10. Now it's time for advanced study. Purchase one good Physics book. I will suggest dc pandey series. Your book must have JEE Mains and Advanced both questions. Also both all kind of questions like integers, MCQ etc.
11. It is also a time to buy one reference book of Physics like sl Arora.
12. Now rigrously solve questions of the book. SEE the solutions when you are stuck. Always learn the new concept which comes in your way while solving problems. Remember students think that they will read book and then they will be able to solve problems. Physics don't work this way. 80% you learn by solving problems.
13. Now follow the routine of giving online tests. Every week. Don't be strict about the topics of test. Just give tests. Even if it contains full Physics syllabus. Whatever tests you have available online. Give one two tests every week. Don't try to score more. Just focus on giving tests. Clear your doubts of test before going for final exam.
14. In 4months solve the entire questions book which you purchased.
15. Keep revising and do class 12 in same way.
