Hello Aju

You still have 8-9 months time and if you work smart, you can really score well easily,dont worry, stay calm cool and confident.

The Perfect Combination of Books:

You should not stress out yourself with multiple books. Instead, you should follow a very simple combination of books that we recommend.

The Best Combination of Books is N.C.E.R.T. + 1 Advanced Book.

You may also refer your state textbooks instead of N.C.E.R.T since they have adapted the N.C.E.R.T. curiculum. Your textbook is going to be your source of basics and your basics should be strong. SO, you are going to use the textbook for strengthening your basics.

The 1 Advanced Book in the above equation is a book that contains advanced-level problems for each subject

 Just remeber Elon Musk at this age and after becoming so much successful, works for 12 to 13 hrs per day.
