Don’t do them in pen.
We know, it seems like they’ve been going on for weeks, and they’ll go on for weeks after this. However, today is officially designated as midterm date by Columbia’s registrar and academic calendar. This means you can no longer ignore them, but you can add them to your list of things to procrastinate. (Or you could be, you know, a good student and study. There’s always that option.)
Whatever your midterm season shapes up to be, good luck!
