Well. Umm.
It looks like 7 people in Class 2 weren’t hooked into the pipeline.
They had access, but they resisted the temptation. The students ‘fessed up to getting answers from someone in class 1. I tossed out the entire exam and used their marks from the midterm test to calculate their final exam grade. There is no cheating policy here, at least one that is enforced, so my only weapons are humiliation and the crappy grades they got on the midterm.
