The first tip is: don't get behind. The problem of studying, hard enough to start with, becomes almost impossible when you are trying to do three weeks' work in one weekend. Even the fastest readers have trouble doing that. And if you are behind in written work that must be turned in, the teacher who accepts it late will probably not give you full credit. Perhaps he may not accept it at all. Most teachers believe that it is your responsibility to do work according to a reasonable plan, and they expect you to take it seriously. Little room is given to students that are not able to manage their work and time.
