as we all know, there are three stages in study--preview, study in class and review, among which review is the most important. from my experience,i'd like to talk about the importance and steps of review.

　　firstly, make a review plan with certain contents of subjects at a certain time. second]y, carry on the review plan regularly. thirdly, examine what has been reviewed and make supplement in time. one thing to remember is to keep notes all the time. i follow my review plan strictly and have made progress in my study.

　　it turns out to be good enough. of course, there is more than one way to review. so long as we review regularly we can find more ways to improve our studies.
