Hii!
As the board exams are quite near now, what you can Focus on doing is solving previous year question papers and sample papers. That will help you give an idea of the pattern of the exam and the way, the questions are asked.  It will also let you know the important topics so that you can Focus more on them. Try clearing your concept and make short notes. Revise every day focusing on the subjects you feel little tough. Be serious and study with dedication now.
Hope this helps.
Good luck!

Hello,

Whether you belong to 10th or 12th, preparation is necessary to get even passing marks. I will tell you the the tried and tested formula to get passing marks or maybe even higher,

1. Focus only on your studies, use your mobile only for education purpose,

2. Download (or purchase from local market or bookstore) 10 years previous question paper

3. Understand the question pattern, try to analyse question section (like subjective questions are consists of what marks and objectives questions are consists of what marks), read according to that.

4. No need to be bookish, just read and understand the concept,

5. But learn the points otherwise even if you know the answer you won't be able to answer the question.

6. Revise 2 or three times.

7. Sleep tight at night, give rest to your mind also.

Good Luck.
