I don't know why this antididactical bullshit is tolerated in STEM or even praised. Every single research in the field show us that feedback is one if not the most important part of learning, that's why self teaching is so difficult, but problem sets without solutions, no guidance on how to approach problem solving and, my favourite, fear of memorization and firm knowledge are the rule in that world. They were just annoying, frustrating, full of themselves and generally poor teachers.
