@inthehands One observation from my experience. My freshman year of university, we started with 60 of us in “Honors Calculus” and finished the first quarter with 8 students in the class. It was a tough class, but the instructor had done it before and had grade brackets figured out for his material from previous years. The 8 of us finished with A and B, and I think the class mean was about 3.4. All well and good. 1/2
