exams...why?

i think, no matter how creative the work is in a classroom, so long as we are in an exam set up, we are still dancing in a 4 x 4 small cell.
the destruction through the exam set up turns every free flowing educative work to a limited problem solving work.
the suffocation of finitude..?
why exams?
what purpose do they serve?
when we will wake up to the sheer destruction they are causing all over?

and what we do in the meantime!
