As an example from my math undergrad days, I remember the Topology I class as having been notorious for its highly bimodal "dumbbell curve" grade distribution: you either understood the key concepts and got a nearly perfect score, or you didn't and were lucky to get any points at all. Very few people ended up scoring anywhere in the middle between those two extremes. | |
