gollark: But schools really do like the whole "memorizing random stuff" thing.
gollark: You would HOPE so.
gollark: My school (not university, I think the equivalent is high school or something elsewhere) is handling it *somewhat* okay, but possibly partly because it would mostly be revision for the (now cancelled) GCSEs anyway at this point.
gollark: Surely at least part of the point of the grades you get from school/whatever is to show that you're actually qualified to do whatever subject it is.
