plzz give some tips for revision in maths.

Hi,

Study the theory first and than start solving problems. Start the problems from basic and than move ahead.
Pick any one book for JEE and try to solve al;l the questions from that book./
Pick only one chapter at a time.
Make a concise notes that you are going to refer while solving questions.
Refering them again & again will help u in remembring them.
