Exam in My Eyes
As we all know,when step into the school,the exam is already come to us.We spend everyday to study lessons,review the note,do the homework.
Maybe some people say that student can't do anything except having exam,which means except exam,students shouldn't do anything that have nothing to do with the exam.
However,exam is a important tool to exam students learning ability.For example,what students have mastered ,the weakness of the knowledge.Exam can help students find out their faults and let them take more heart into study than before.
In my opinion,students can learn lots of things from the exam,not only the knowledge from the books,but also the skill of how to have the exam better.
