You know I've been lucky to have experienced three radically different types of education when I was a kid.
I went to public school in Sweden for 7 years, private school in Switzerland for 3 years, and then 2 years of public school in California + god knows how many years of College.
Ignoring College and the private school (they are just too different from the public schooling system), it's easily said that the Swedish public schools are just far superior in every way to the American because of two things.
1) The classes in Sweden are more intense, broad, and demanding. As mentioned in the original post, at one point in my schooling I was taking 4 languages at the same time (Swedish, English, Spanish, German), and this was before high school! My Calculus class in American High School was covering math that I had done in 7th grade.. I mean it's crazy how much you learn over there!
2) The classes/schools are MUCH smaller. Imagine the shock when I went from a 350 person school to a 3,000 person school! (And I'm not talking about College) When you have such big classes, the teachers have to grade a shitload more, often leading them to resort to handing out Scantrons (another sidenote: I believe Scantrons is another reason why education in America is so crap...fill in the bubble for the 4 choices? What is this? Who Wants to Be a Millionaire? In Europe EVERY single test I had was Written Response, not only making sure you knew the answer and not just guessing, but also helping you develop your writing and reasoning skills)
Sorry for the Cool Story Bro Post....thought I'd give my 2 cents on this because I've experienced both sides ya know
