In response to Singaporeans maxxing out class limits... I wonder if it's because somewhere along the way we actually accumulated a love of learning.. or rather never lost it in the first place. One of the few things I like about the Singapore system is that, it's actually okay for you to be good at school work rather than social poison. Of course the problems come in when you realise that all singaporeans care about is schoolwork. but possibly the first is what made us the way we are... wanting to learn too much :-p
