The thing is that this is a zero-sum game. These schools aren't providing education. It's not about actually improving yourself. It's about getting the highest possible score on the gaokao, nothing else at all. If they were actually helping students further their education I'd agree with you. I've been to these kinds of schools and I have friends who did for even longer, and they really, really suck. It doesn't help you in any way, I'd say it's a net negative in terms of education for most.
