Wow, that's cool!
I'm currently a senior at a Gymnasium in the canton of Zurich. (I will apply during a gap year). I'm taking 3 SAT II's this Saturday at an International School as well

(you'll recognize me for I'm the only one who isn't chauffeured with a Jaguar/Bentley, etc. to the school -- this place is crazy, you'll see it.)
I'm applying to some schools on the East Coast (Ivy League, LAC's, others) and probably Stanford. If I don't get in anywhere (which is likely since I'm only applying to highly selective univs) I'll be happily attending the University of Geneva (I want to study International Relations and there is no better than Geneva for that).
Good luck with your SATs and with USC (their cinema program is awesome and much more selective than the rest of the college, isn't it?)
