Firstly go through the basics of 11th & 12th  and try to revise it again and again.

Try to solve the previous year question papers as well as mock test series if possible.

Best of luck..!!

Hello Mukesh.

Atlast practice, practice and practice.

Hey Mukesh,

These 10 days are very important for you.So, don't waste even a single minute of it. In these 10 days try to  do below things:

• Practice JEE Main  question papers of last 5 to 10 years during 9AM to 12PM everyday and evaluate your performance.
• Try to avoid silly mistakes in your paper.
• Take a blank big chart paper and write all formulas of Chemistry,physics and mathematics.
• Don't solve very  tough and time consuming questions provided by coaching  institutes and your friends because that's only going to demotivate you.
• And at last,Be confident and have faith on yourself.

All the best!!

Hello Mukesh.

There is not much time remaining for your exam. I suggest you prepare for Boards as if you are preparing for JEE. Understand the concepts. This will help you in writing the theory paper in your board exam, as well as solve examples in JEE. 

In this way, you are preparing for both the exams. Relax. Stress can be harmful in this period. Maintain a list of short term goals. Like 2-3 chapters of PCM each daily. Complete them in your deadline. Understand them fully. Then take 1 question from your HSC board text book and try to answer it. And do the same with your JEE reference book. Take one numerical and try to solve it. If you can do this both you are good to go. If not, then you will understand whether you need to focus on theory or numericals.

By the time your board exam ends, you will be fully read for JEE as well. 

Keep the last 10 days for revising. 

ALL THE BEST.
