My son is in 9th grade in Switzerland, at an international school in Zug.
His P.E. class meets in the English Room (for theory lessons).
His English class meets in the Humanities Room.
His Humanities class meets in the Math Room.
His Math class meets in the Physics Lab.
He's taught German in the Library.
His tutor group gathers in the Computer Lab.
Drama erupts in the Dance Room.
Science meets in the Chemistry Lab - wow, one that makes total sense! Except Jason says he's not doing chemistry, it's biology at the moment.
His French class meets in a room called "Aula East" which is neither here nor there, as these things go.
I don't know how he keeps it all straight. Habit, after a while. But I do find this class placement hard to fathom. I think it has to do with the fact that the school building is small for the number of classes, and it has been growing fast. The school is in the process of building a new, larger facility, which I am sure will have less confusing classroom names! As long as the teachers keep straight what they're teaching, everything will be fine. A rose by any other name...
