writing in other classes...

i have a 1000-1200 word essay due tomorrow in my philosophy class and it is something that i wish we could have the same kind of work that we have in english class. i want to be able to have other students read it and give me suggestions about how to fix it or add more to it. i know they have the writing center but i always feel embarressed to go and have someone else read my paper. im very shy about having people read things that i write. hopefully i get a good grade in this class and hopefully my philosophy proffesor will love my essay.
