WHY DO WE HAVE TO DO EXAMS?

I don't understand why we do exams, an exam is only a piece of papper and everybody gets nervous, me too. You study four or five hours depend the subject and after during the exam yout mind blank, and I would like to propose to do a project, orals presentation of the chapters of the subject and only do exams in chemistry and maths and that's all.

Often when you finish the exam, the firts thing your want to do is forget everything and have a rest . In my opinión it is better to do exams during the firts hour or after break time, because in the morning your mind is fresh and after break time because you can revise.

In most exams, there is not enough time to finish and even less for revising and after the mark is bad. For exapmle: Spanish, Maths...

From my point of view exams are necessary but not for all the subjects. I whope when I am older and if I go to univerisy I will see things differently because then I will be studing what I really like.
