Hi Harshitha!

It is not clear whether you are in class 11th or want to revise class 11th syllabus and are in 12th. I am going to assume the second scenario holds true.

If you are currently in class 12th, it is imperative for you to chart out a revision timetable so that you can do timely revisions of class 11th course. Remember your mind is like a sieve and you will need to revise many times before you are finaly able to be sure of the topic. Read Biology NCERT as many times as you can and pick up good reference books for physics and Chemistry. Write down organic chemistry's reactions/formulas etc and revise that every night before going to bed. For physics, Practice is the key! You won't be able to get any benefit if you read text, you will jave to practice to solve problems and tackle different kinds of questions. Arihant has good books for practicing Physics MCQ's.
