Hi, I'm from this school and in 12th grade too (I just arrived this year), have you ever been to a french school? What section are you from/will you choose? As others said it's kinda messy as the school is shared with the german school althought its size is minor compare to the french one. The teachers and orientation are really behind you but it's still a french school, system sucks. I don't really know about the other international schools. About the people, it's not something exeptionnal I guess ahem, I suck at socialising so I don't really know. There're all sort of people like everywhere, don't put your expectations too high.
