Fortunately no! Or unfortunately, depending on your perspective. They voted on the issue on the first day of class, and since it's an elective it's dominated by very motivated language geeks who wanted a chance to practice their second language (English) in order to learn their third or fourth or whatever. And the teacher speaks both Chinese and English equally well and didn't care, and I was honestly pretty relieved.

My classmates still discuss stuff in Chinese though. Sometimes we do that lazy thing where they talk to me in their native language, and I answer in mine, and we all sort of understand each other.
