I've been very concentrated on my research in the past couple of weeks and as a result I fell a little behind in terms of grading. I make students hand in a written assignment for every day of class in each one of the classes. We also wrote a mini-quiz and a composition this week.
So today I put all of the papers I need to grade on the floor, and they reached higher than my ankle. I'm literally ankle-deep in grading. I need to get on this now, before I end up knee-deep in ungraded assignments.
