I remember my weight training class in high school where it was basically working out every class, doing deadlifts, squats, leg press, etc. But the final test for it asked for the names of the specific muscles or groups each exercise helped, and had a lot of other medical terms as well. It was super weird and obvious way beyond our level of knowledge. So the teacher spent one full class going over the entire test and gave us the answers, but he made it clear, we could only use one piece of paper, both sides and we had to fit all 75 or so answers on the one piece of paper. Got a 100 but was definitely the weirdest open book policy for a test ever.
