I was in an introduction to c course with a prof who had a midterm where something like 7 of the ~120 students of the exam passed. The other cohort from a different instructor was pretty standard bell curve. It was a royal mess. Each prof. wrote their own exams but the 7/120 teacher was brand new and wasn't afraid of throwing in odd-balls. At least in his defence, he wasn't being malicious or callous but just wasn't supported enough to pick the right level of challenge.
