As is vividly shown in the picture, a college student tries his best to read a lot of books in one day in order to cope with final exams.The student feels tired and depressed because he doesn't believe that he can finish it in such a short time. Nowadays, this phenomenon is prevailing in our society. Students enjoy their life during their spare time, However, when final exam comes, those students have to cram for them. There are a lot of disadvantages to this approach. For one thing, students can‘t truly acquire knowledge when they consider the exams as emergencies need to be solved. For another, Finishing all the work in one day is harmful to our health. After finishing our exams, we may feel exhausted, even fall ill. As far as I am concerned, as college students, we should preview and review knowledge during our spare time, only in this way can we truly gain knowledge. In addition, we should focus on our learning method, after all, If we chase our aims too fast, we may fail.
