gollark: Well, they seem to have tried to do that initially for a bit, then gave up (at least for my year), leaving us doing something like two lessons a week but being set a bunch of random papers to do (which I mostly ignored because they are extremely boring).
gollark: I'm glad school is over for me now and I can avoid worrying about them doing stupid things.
