I used to teach at a university here in Paris. And we had classes of about 30 students. So that's too much. I mean, when it gets to that number, it gets difficult to actually manage the class. You know, as you know, we don't just have one teacher at the front and then all the students sitting facing the teacher and taking notes while the teacher talks. But for a good language class, you want a much more decentralized sort of classroom.
