What did you expect?

There was a hullabaloo recently over grades at Harvard University.  Well, found a university long ago, make its name synonymous with knowledge and intelligence and run it for several hundred years. Let all the faculty members there strive to be efficient, successful teachers, let all the students be the sharpest, most achieving students.  Then grade them.  Oh, no!  Nearly all of them have earned the highest grades!  Whatever should we do?
