recitation
This must be unique to NYU, because nobody I've talked to at any other school has heard of it. It's a small group of people from a larger lecture who have to meet with a grad student for a smaller class session that allows students to discuss the material covered in the lecture.
Example:
I might possibly pass my liberal art class because we discussed the lecture in my recitation.
