In France, a typical primary school will have between 100 and 200 kids total maybe 250 in Paris but that would be a large one. A middle school will be between 400 and 800 students and a high school around 1000.

1000 kids / class year is unheard of. That seems huge to me to the point I can’t understand how it would work. I knew mostly everyone in my class year up to high school and even then I probably knew more than half. Might explain why the social scene is far less brutal here than in the US.
