I’ll add: go to the TA study sessions. And try to answer questions in class. Even if you have nothing to ask, use that time to do homework, listen to other people’s questions.

Yes, you’ll learn more. Also, TAs will recognize you put in the effort so if you’re arguing for partial points or you’re really close to a cutoff grade they will be more likely to bump you up versus someone they’ve not seen or noticed all semester.
