Sorry, Arlen, I read too quickly and seemed to see "must have at least one D-" - maybe I was thinking of one or more of my students !

, though now that I think of it, if one of them had read something I require them to read for class that quickly and made such an error I would have let them know it. Though on the other hand, I was grading their papers and quizzes which is why I read things in a hurry on the Forum.
So it all evens out !
