I was a science writer in college; had my own column in the Features section! Although I wasn't an english major or anything, I would be willing to critique a few personal statements. Don't expect big picture stuff or advice about content, but I can give grammatical advice, help re-word sentences, etc.
Might be easier if you send a particular paragraph that you are having trouble with and any sentence before and after the paragraph (for transition help).
I am just offering!
Good luck to all!
