Just simple. If you have just entered in board class the start working hard from very begining there is no need to be panic that "Xyz is going to that tution i must to." and many more. My advice will be that you remian at home and every night you read one scene of play or one whole act or story. You like. Grammer must be done every day during day time and if you stuck at some question do clarify your dobts and don't reveal anything that you study this this much during night. For board you need to be selfish.
Best of luck.
