Firstly I would suggest you to go through well with NCERT books because it will help you to build your concept. R.D Sharma is best suited for BOARD level and MAINS level so you can go for it. You can also use TMcgrawhill.

Here are some important tips you can prefer:

Create a practical study plan
Students usually spend more time in planning than actually executing those plans. Planning is art of the possible. So, create a plan which can be successfully executed. Give more time to topics which you find difficult and keep a buffer so that you can complete some pending tasks.

Know your strength and weakness
Everyone has specific strengths and everyone has specific weaknesses. It’s pretty certain that if you are not clear on your weaknesses then you are not clear on your strengths either.

Practice previous year papers
Practicing previous year question papers should be left for the last couple of months before an exam. These are actual questions which have appeared and you should time yourself while answering them so that you can compare your scores.

Learn all the shortcuts
Every student has shortcuts which they use during preparation. Be it for remembering formulas or memorizing charts, use shortcuts to save your time.
