As far as I know, time is not always enough all of us. So first of all, you need to arrange your time good. You’d better to make a long-term study plan. That is to say, an one-month plan with more efforts to take up his weak subjects. And a short-term plan is equal necessary, if not more important. You have to make sure what you need to do each day, each class or even each minute. At the same time, it’s quite essential to keeping healthy. So take exercise for at least one hour and sleep for no less than seven hour a day. And don’t forget to eat well. More fruit was always right for you.
