Chinese parents take special attention to exams and some teachers measure students mainly by exams, while in western countries, exams are necessary but not the only thing for students. The different attitudes towards exams decide what the students will be in the future. Now more people have change their idea about exam. They take the positive opinion on it. This is a good side. The value of exams is not to judge students, but to know how to get improved, so that they can do better. A student who does well in getting high mark doesn’t mean he is doing well in other sides.
