I was a tad skeptical when I saw "It's all free." Technically, that's how it is here, but that system doesn't work. Or do you mean that its funding doesn't even come from taxes? Also, when you say you can pick courses from any school, does that mean you can take whatever classes you want? Because under the NYS Regents Diploma bull, there's a required 3 math, science, history, and language credits, plus electives. There's no leeway for those who know what they want to major in college, no breathing room for those who hate the "same old, same old". And there's not even that much to choose from in the way of electives. Say you'd like to learn German or Latin. Nope, it's not provided. Maybe you like Ancient History? Nope, there's no class like that either. The only elective I'm taking that isn't a generic art/music course is Short Fiction. And they offer over twenty electives- 5% is terrible statistic.
I think that would be a great system for me, other than the language fluency requisite. Sometimes I may think that schoolwork is too demanding, but that's because of the fluctuations in expectations. In one state-required history class, I'm rewarded for even showing up. In other classes, I'm expected to memorize and recite the whole periodic table. But, if the bar was set to a high standard, I think I could deal with it, because in most of my classes, I know more on the first day than the teacher expects me to know five months into the semester. I just happen to like facts.
Plus I'd be that much closer to the Swedish metal scene : ]
