We had an exam that was either pass or fail, no grades. The professor and censor would kick you out with a "PASS" in five minutes if they felt that you had sufficient grasp of the topic. Some found it a bit offensive, I just loved how efficient it was. I happened to hang around on the first day of their planned three days examination and the professor just popped his head out the door and asked if I was ready now (a day and a half early), sure... I guess. Five minutes later "PASS. NEXT!"
