Ha, I should have realized you were an insider. :) Your timing was much luckier, since you had those 2 years built-in, although I'm not sure whether you got to skip a grade when you came back, or had to "downgrade" and sit those two years with lowerclassmen, while your classmates remained a grade ahead. That would have sucked.
Anyway, the fact that you also went back to the US after graduating validates my last point -- yet another "future leader" failed the "task". ;)
