timed writing

i think they only thing that timed writing can be used for is to see how god students can comprehend a prompt and think of ideas quickly. not how good they write. the its not like a paper you get to think about and research its a prompt you don't know a lot about and they want you to burst out 3 pages that they expect to be great writing. well if you cant revise it or research it how could it be very good. i dont like the fact it is a graduation requirement. i think its stupid. how can they judge how good i can write or anything based on a prompt they give me and say write three pages and if you pass you graduate.
