The hardest class you've ever taken.

[Jackalope]

It's not the classes... it's the teachers.

My most maddening class was Digital Logic & Theory. The class was maddening not because the material was hard (it wasn't), but because the professor was incompetent - it was as if he was learning the material two paragraphs ahead of class.

I already knew the material, and he made so many mistakes during his lectures that the rest of the class struggled through the lab work during both units. Aced the exams, aced the labs, earned a B because I declined to attend his useless lectures after the second week of the first unit.
