Exams are the only way to test a person's knowledge objectively.

The exams are over. But the question is are exams really good to test a persons knowledge objectively?
I think it is a very well way to find that out. Exams are not about one themes, but bout a lot of different themes. If it was about one theme, than it was a bit easier, because if it was a subject that by any chance was easy for you, than they wouldn’t know what your knowledge was of all the other subjects.
But there is only one thing I disagree with, it is not the only way to test a person's knowledge objectively. There are a lot of other ways to test the knowledge objectively. What did you think about all the tests there are in a school year. All those tests are a very well way to test a persons knowledge to. Only on tests there are al lot of children who copies from a crib, or from others. And when you do an exam there are three teachers who are watching over you and the tables are a meter apart each other. So there is no way of copy en cheating.
And in a test is only one theme. And at the and of the year you don’t know what they still know of those themes. Because they learn a couple days before and a couple day after the test they lost the most.
So maybe an test isn’t also a way to test a person’s knowledge objectively.
But than there are testweeks. That is a week with only every day tests. There are a couple of themes in one test. The tables are a half a meter apart and there is a rigorous control. Almost like an exam only less themes. And one teacher who does that rigorous control. There is only one disadvantage, the teacher can’t watch al the students, even though he is in the front of the class. So there is still a small chance of cheating.
So maybe exams are the only way to test a person's knowledge objectively. There is no cheating possible, because of the three teachers and the rigorous control. And because of the different themes.
