<p>When I was in South Africa a couple of years ago, I helped an engineering professor grade some of his exams (just figuring out the scores after he marked up the tests). He asked how it was going, and I said, “Well, the students didn’t do too well. Most of the scores are in the 70s, and no one scored above 90.” It was a BIG class, too. He said, “Actually, those are really good for an exam here.” Apparently, they grade much tougher over there!</p>
