Marco is the best. He is a super reasonable TA that wants everyone to do well. The material is easy and he won't give busy work or make you do an assignment if he doesn't find it helpful. He will laugh at your terrible pronunciation, but you probably deserve it and he's really funny so it's all good. Also he can't pronounce the word "uncomfortable" in English so do with that what you will. Definitely take this class; I learned a lot and it was not difficult.
