return if (Math.random() > 0.8) "Glückwunsch: bestanden" else "Schade, try again"

Would it make sense to reduce the cutoff for passing to 0.5, because at this point, the chance of passing is theoretically higher than failing?

Well currently the chance of failing is ≈ 80%, which is reasonable for theoretical computer science
How about a second endpoint? Maybe a programming exam with a 90% chance of passing and a theoretical exam with a 20% chance of passing?
Seems to be more realistic

Ah, you're right. I assumed the chance of passing to be a perfect 0.5
We could gather some data about real-world exam grade distributions from open sources to model our predictions more closely to reality.
