Strangest semester ever?

(Of course, of course: **strangest semester ever** ***so far***.)

For years now, we have been working on inverting the former bell curve distribution for student grades, with results polarizing, and clustering at each extreme.

This semester, however, I have 5% over-achievers and 95% missing-in-action. Even the graduating seniors have gone on permanent vacation, it seems.

Anyone else?
