Hi Jagnnath,

Math- NCERT and RS Agrawal or RD sharma is enough. Solve problems of this book.

After that try to solve previous year questions 3 times . Because almost 20% questions come directly from previous year questions.

Keep in mind you have to solve 150 questions in 3 hours.

That's it… Don't wait for last moment. Prepare from beginning. It is not too easy as well as not too tough.

Good luck!
