Unfair exam system should be abolished

Nowadays, examinations have become the focus of education.

A student has to pass an examination before he can be promoted or graduate.

If he fails in an important examination, he will probably lose the opportunity of getting a good job in the future.

I think this is unfair. Examination results cannot reflect one's ability.

Besides, people are misled into thinking that examinations are the best means to measure one's knowledge.
