Tl;dr at the end.
Some background information.
Back when I was in high school, I took a standard physics class from a teacher (Physics Dick, or PD) who liked to push his power around. This resulted in a lot of rediculous rules. My favorite was the rule that a student had to spend at least one minute on each question in a test; if we turned a 40-question test in 39 minutes after PD handed it out, we’d be docked 20%. The policy was supposed to encourage us to be careful with our answers or some shit, but it frustrated me to no end. I had a pretty good mind for physics, so I always finished my tests fairly quickly. I had to stare at a wall for 20+ minutes before I could turn my test in and bring out a book to read. Not a huge deal, but still annoying.
