edgeCase

Those weren't the course notes. That's a wiki for (and from) students and TA's, mostly. One semester's course notes are here:https://colormygraph.ugrad.cs.cmu.edu/anupam/

The lecture that discusses finite probability distributions is at: https://colormygraph.ugrad.cs.cmu.edu/site_media/static//cou...

You can count math studies as up to 5 classes, since that's the number of normal-track classes it covers.

Also, having TA'ed graph theory for pikhurko and mackey, and having TA'ed 251 twice, I still see 251 as the hardest.
