> We had an economics teacher in college who was famous for asking the engineers to stand up on the first day of class and then stating that they would be excused from the finals as they would all have above a 95 and not have to take it.

To be honest with you, that teacher sounds like a real tool. All that that can possibly achieve is to breed various subtle forms of animosity, either among classmates or towards engineers or towards the teacher or the course.
