I just posted this June 3rd BBC article "How US students get a university degree for free in Germany (

I think the BBC gives a good breakdown on the costs for US students. Interesting that most of the classes are in English. Now, I wonder how much the situation is different in Denmark, Finland, Norway, Sweden, Iceland, Argentina, and other places - to Germany.
At the moment, England and Wales have fees for university students; students from Scotland do not pay fees at Scottish universities (I'd move to Scotland in two seconds IF I could or dh could get A job). However, the fees for universities in England and Wales are still considerably cheaper than in the US.
