Students vary in how they end a course. I've seen some dump their notebooks in the trash as they leave the examination room (Really!!). Others save their notes and textbooks. Many students sell their books. Everyone experiences a course in their own way. Students vary in what they learn and ultimately take away from a class. Before you file you notes away, throw out your notes and papers, and/or sell your textbook, spend a little bit of time evaluating what you have learned and what you should do differently next semester. "Close out" the course by doing these three things.
