I see what you mean about asking about the 3 pages. Well, it is great to give them an amount that is consistent with what they ask for, obviously, and... instead of being courteous by making it quick and to-the-point, you can be courteous by writing something that will be a real pleasure to read!
In regards about assistance with the essay they say: As this essay may be used to assist in course placement, students should receive no assistance in writing or editing the essay. What should I do, my family does not speak english?
If a school does not believe in allowing learners to seek assistance, it is a sorry excuse for a learning institution. However, the mistake being made by this school is an understandable one! It is not surprising that they would make this mistake, because obviously you are supposed to be being judged by your essay.
It is the same way we judge presidential candidates by their speeches. We watch their speeches so that we can judge what they say, so it would be ridiculous for politicians to get help with their speeches... :-)
But it is indeed a mistake. Schools should understand the admissions essay as a learning process with its own absolute value. Schools should not be merely concerned with weeding out the struggling writers.
This forum is an example of a place where all people -- not just people with language barriers -- can come to collaborate.
It is no good to resort to, for example, paying someone to write your paper, because that is the lazy way. But on the other hand, it is foolish for school representatives to think anyone would EVER submit an admission essay without seeking some help, even if it is just for a proofread and some feedback.
Anyway use these forums in any way that will help you, even if you don't want to post what you write. I understand your concern!
