Hello student, 

Since you are planning to start this early in Class
9, Sheer practice and determination can take you a long way in acquiring that
talent and beating those aspirants who are gifted but don’t do their share of
hard work.

If you want to prepare for competitive exams then
prepare for NTSE and various Olympiads. this tremendously
helped me to understand the competition around myself. Solving mental ability
questions which were a must for NTSE exam really helped me a lot to tackle
questions/ develop a solid problem-solving approach which is required to crack
a competition Like IIT JEE or NEET/AIIMS.

Moreover, right now if you want to initiate your
JEE preparation then understand the basics of your chapters well as
you are going to study advanced version of these chapters in 11 and 12.

Physics: Start with HC Verma. Then go ahead
with IIT JEE Questions directly. Also other
books from Arihant and GRB are good .. However if u have time left after doing
previous years, you can solve Irodov.

Chemistry: NCERT most important. Other than
that, for reference, use OP Tandon. Other books from GRB and Arihant are also
good! Do mole concept and stoichiometry as that is very important for JEE purpose.

Maths: Start with NCERT and then complete RD SHARMA. You will find it very useful for school as well as JEE purpose. Advanced
Problems in JEE (Balaji) and then previous year questions from Arihant 39 years
can be helpful in future.

Cheers!

Hello Swarup,

I will write about the books I used. Note that I mostly relied on books and self study and so, I literally had a library of books with me. You are definitely not expected to purchase them all.

Physics:

Concepts of Physics Vol. 1 and Vol. 2 - arguably the best book for beginners

Mechanics Part-1 & 2 by DC Pandey - the best book for rankers

Understanding Physics Electricity and Magnetism by DC Pandey

Understanding Physics for JEE Main & Advanced Optics & Modern Physics by DC Pandey

Understanding Physics for JEE Main & Advanced Waves & Thermodynamics by DC Pandey

You might rather want to buy the complete set of books - Understanding Physics Series (Set of 5 Books) by DC Pandey

Problems In General Physics by IE Irodov - buy this book if you want some challenge

Resnick Halliday - a great book for theory and non trivial problems

New pattern Physics Book by DC Pandey - a great book for problems!

Good Luck!
