Editing
Being up at college you make a lot of friends - and you make even more if people know that you can edit their papers for them. Especially right around the time that research papers are due, I have a lot of friends right around then. But I really don't mind! I love editing and I've discovered that reading friend's papers has become one of the best ways to learn a little about a lot of different topics. The following are some examples of papers I've edited over the course of this last semester.
An analysis paper written by a fellow student on a short story by Nathaniel Hawthorne. She asked me to edit it for her and the comments are my points and notes for her paper.
A scientific analysis written by a fellow student on corn production. He asked me to edit it for her and the comments are my points and notes on his paper.
