Dear Atul,
You should use the last few months effectively and intelligently and with proper time management and hard work you can get the desired results. Firstly, I would suggest to complete your NCERT textbooks. You must have clear understanding of the topics and concepts.
Time management is necessary. Students don't get enough time for self studies as they are only busy with the coaching classes. But, Self study is also very important.
Devote time to each subject. Try to finish your course early and then you will have enough time for revision and you can practise and check your preparation in the pre- board examination. Revision is must. Writing down important formulas in separate notebook is useful during revision.
Practice previous year question papers to have an idea about the types of questions asked in the examination. Practice sample papers, it will also help you to increase your speed and manage time well in the examination.
Lastly, stay positive, focused and healthy. Don't take stress. Remember, we don't get anything easily we have to work hard to achieve success.
Good luck!
