I've studied German for a total of five years (seven/eight at the end of my schooling if I hadn't dropped it) and it's nothing you want to pick up just for the heck of it. I'm Swedish so a lot of the vocabulary and pronounciation is already there (the easiest parts of German), but I am horrifyingly bad at grammar and the German grammar downright confuses the heck out of me, and considering I can't even understand the grammatical rules governing my own native language of Swedish that's pretty bad
. I can, at the very most, order food and ask for directions :P
German is one of the coolest sounding languages in the world though, but if there aren't any real classes your German would be limited to something like this:
Ich hätte gern eine junior tüte und ein klein cola
Or something like that.
