Please bubble in your name, last namefirst. Please be sure you use the name with which you are registered here at UIC and not a nickname. Ifyou only learn one thing from college, please learn that whenever you fill out one of these forms, youshould use a #2 pencil. Pen just won't work. Really, it won't. Good luck!
