Just curious! I taught a semester of graduate school a few years ago, and I will never be the same haha!
It was harder than I thought. I've done a kajillion hours of tutoring, but was surprised at how different it was to teach while standing in front of a room full of students. You really have to command their attention and respect. It was an eye-opening experience.
I will probably teach again, but not in a university setting.
Anyway, I'm curious: how many of you guys have taught before? What was your biggest surprise?
