This is the point when many good writing students seek help from writing tutors for one final proofreading. They have finished their papers, they have developed a thesis, and they have addressed organizational matters. Now they need to do some editing work. This often places the tutor in an awkward situation because the Writing Center is not a drop off service, but rather a place where students learn how to edit their own work. And often because it is easier to fix a comma splice than to help a student with organizational problems, tutors  correct the errors for the student. Try to avoid correcting a student’s paper for him. Instead, take the opportunity to teach the student so that he can learn to correct his own work.
