One thing that struck me while reading this was the influence of American culture. You often see school depicted as a sort of weird jungle with jocks-vs-nerds dynamics coming from America. Some of the kids at my international school emulated that and it wasn't pleasant, but I got over that eventually as well.
In general, most people I know across cultures think back fondly to their school days, minus Americans. My American friends are the ones most likely to point out the things Ian mentions. The jumping through hoops, wastes of time, the production of wage slaves.
