The Use of Examinations

A good education should make people think for themselves. But the exam can never do anything like that.

First, examinations are second to none because it brings anxiety to students. As soon as a child begins school, he enters a world of terrible competition.

Second, exams do not interest students to read or to learn widely. They do not help students to look for more and more knowledge, but try to put as much as possible into the students’ head.

Third, they lower the standards of teaching, for they do not give any freedom to teachers to decide what to teach. Teachers themselves have no choice but to train their students in exam techniques. The most successful students are not always the best educated but the best trained in the technique of exams.

Fourth, they can tell you nothing about a person’s true ability. The exams are often nothing more than a subjective assessment(主观评价) by some examiners.

However, if there are no exams, few students or even no one will do any revision or study!
