Dear Li Mei,
With the mid-term exam come, you must get prepared for them. I think that you need is a right study method. As we all know, there are three stage in study--- preview, study in class and review, among which review was the most important. You should first make a review plan, then stick on it. I follow my review plan strictly and have made a progress in my study. It turns out to be good enough. Of course, there are more than one way to review. So long as you review regular, I’m sure you can find more ways to study well. If you have any question about subjects, ask me I’ll be glad to help you. We may meet in our school library every Friday afternoon.
