“Proofreading” invokes the image of a teacher with a red pen bent over your paper, fixing every misplaced comma.  As mentioned above, that’s not exactly what we do.  A writing center mantra holds that tutors should help the writer, not the writing—and the best way we’ve found to do that is to work with you on a few skills: say, organization and paraphrasing, or thesis-writing and avoiding fragments.  That way, you leave knowing how to strengthen your paper in several key areas and how to strengthen future papers in those areas.
