Well that sounds a lot like the danish "efterskole"
Oh, wait a minute, just had a look in the dictionary, it means "kostskole" witch is not the same. "Kostskole" is the place where you send kids who can?t behave. "Efterskole" is more like a place hippie kids go to learn how to smoke weed while they sing socialist songs around a campfire and after that they sneak of to the girls apartment in the night (and sometimes they get caught and thrown out of the school). I would have loved going to "efterskole" when i was that age
