Clarification regarding tomorrow's "extra class"

There was a question today as to whether the material to be covered in tomorrow's extra class will be "on the test."

My flippant response was possibly driven by the fact that  I am always freshly surprised to find out that there actually 

might be students taking one of my courses with an eye towards  their GPA (clearly, ASU student corporate memory/social networking

isn't all that it is cracked up to be :-).

Thinking about it again, I can imagine some students being unduly inconvenienced by having to keep up with an extra meeting that they haven't bargained for, in the last week of classes. 

So, I will certify that the material covered in tomorrow's lecture will not be "on the test". 

cheers
