From a student:

Hi Prof. Art. I was in your class and I just now looked at my grades and I am really not understanding my D in the class. I did all of the assignments and participation and my grades dont look bad. I averaged them and it looks like a C to me. The only thing I dont see on there is my Final exam part 1 grade but all else looks right. I am just a little confused, I thought that class was going well and I was doing well.

-Confused.

So I went back and crunched the numbers. Hey, I ain’t perfect, I’ve missed a number before. But the facts remained:

In fact, Confused had missed one weeks’ worth of participation, and one assignment. Part One of the final was never opened, nor attempted, according to BlackBoard.

And in fact, the numbers crunched to a 57.

Which is an F.
