Do you agree?

I believe that mandatory tests are not necessary, because we spent six hours five days a week at school, having to go to bed early, and waking up early! We spend a quartre of our lives inside studying or listening to a teacher none stop talking. I think six hours of school each day is enough studying, not these mandatory tests we have to study longer and harder for. As a student, and as my own opinion, I think mandatory tests are unnecessary.
