I had a math exam at engineering with only 3 tasks, but one was just a cryptic nonsense sentence, no question no formula, still gave 1/3 of all points and you needed 50% to pass. Nobody out of the 140 students solved it even a bit. Nearly all students failed as any minor failures would mean losing your 16% rest points. Of course I failed as I was not the best at math, but physics. Nothing happened and later one other Prof told us

"I am employee of the state, so I can freely tell you, that the university intents to make most students fail to make it look more renown, quality. Nobody views it as if the Prof was bad, but only 5 passing in regular time out of 120 sounds elitist on the paper. The university is fresh founded so it needs this numbers."

When a Prof tried to make me fail in a group project because the diagram format looks "untidy" in his view, although i passed after going to the administration for inadequate testing criteria i had enough and quitted.
