Since we can't predict the board papers,  but we can practice that hard,  so that we can tackle each and every questions. Don't loose ypur calmness , and stay relaxed and focused . Don't panic after seeing the paper else ypu will forget the topics which you know properly.

Hello,

It is very important to understand and clear each and every concept of the subjects you have in order to maximise your chances of scoring 90+ percentage in Board examination.

You should go through the theory portion of each subject and revise them periodically to get a better understanding of the subject. After that you can solve some sample papers and previous year papers, that will help you scrutinize your mistakes and after analysis you can understand your weak points and then work upon it.

Doing this much with utmost dedication and punctuation will ensure you a fantasy score in your board examinations.

All the Best!

Thank you.
