If you want to do any good in IIT JEE or any exam you need to limit your study material but do that material 100%.

For Maths:-

First clear concepts than go through each and every solved example, in starting you will feel that you can solve these questions easily and tend to skip that question, but for clearing concept you should solve all that questions irrespective of time taking.

Some books in my point of view-

Problems in Calculus by Sameer Bansal.

Coordinate geometry and Trigonometry by SL Loney.

Algebra by Cengage publication.

For Chemistry:-

For chemistry NCERT book is must.

First Clear all your basic concepts from NCERT, after that for organic and inorganic follow Morrison and Boyd and JD Lee respectively, but read only those topics which is mentioned in NCERT.

Books For problem solving

physical chemistry- N Avasthi,

Organic chemistry- M S Chauhan,

For physics:-

Clear concept deeply, try to learn behind the scene of all concept.

Try to Solve each and every question of HC Verma by your self.

Must attempt all previous year JEE questions.

All the very best and good luck.
