Are the exams important at school?

I agree with the idea that the exams are important at school, because it's the only way to point the capacity of the student.

It's true that the exams can make some students nervous and because of this they can repeat the school year, but the exams are necessary, firstly to make the students learn and make grow up their level ok knowledge. The exams also help to know if they are able to pass to a next hard year.

To sum up, I would said that the exams has to be done at school. I don't think that school without exams is good for the students because the exams are the keys of the knowledge and make us go on.
