gollark: IIRC they had to invent a grade even higher than A* once.
gollark: Yeeeees, it's quite bad.
gollark: And they do predicted grades for university applications (the timing is stupid).
gollark: Also, teachers have incentives to try and increase grades.
gollark: Instead of setting questions posing problems to solve, a past exam paper I looked at literally had a question asking you to match up "procedural abstraction" and "problem decomposition" and such with definitions.
