HOW MANY AND AT WHAT TIME SHOULD I REVISE A CHAPTER

Dear student,

Basically the chapter revision is totally dependent on you and your mind. There are some chapters which needs more attention and some chapters which need less attention. Now a student's mind is volatile that means for normal student if he /She reads any chapter then it is not possible that he/she will completely be able to solve questions from that chapter for fully understand the concepts of that chapter. And also note that I am not talking about the exceptional students who have photographic memory in which they memorize the whole chapter just by seeing one time.
Basically if you think that a certain particular chapter is difficult for you then the main reason is that you must not have revised properly or you must not have read or you must not have touched that at all. But if you have read that chapter and find it difficult then you have to revise in a particular period of time, that means, you can revise it on the next day of reading that chapter or you can make your time that in a week you would study this chapter atleast one time got 3 days.
Basically if you revising again and again, then that particular chapter which seems tough to you, after revising certain number of times like 5 times, 6 times or even 10 times, you will find it easy.
And basically you must revise all the chapters at and regular interval of time. Also note that some difficult chapters need more revising while some easy chapters need less revising. So this totally depends on you, because after revising again and again, a period will come where you find that you will be able to solve all the questions of the chapter and concepts will be on your fingertips of that chapter. And also note that no chapter is easy or Hard we are the ones that makes them easy or hard and therefore you should revise a chapter as many times until you you didn't get an expertise knowledge of that chapter.
