Swedish is the only language I'm fluent in.
I wouldn't call myself fluent in English considering how handicapped I feel while speaking it compared to Swedish, but for everyday use it's good enough.
Some French. I can understand it quite well, but I have a hard time speaking it, other than to order in restaurants and simple things like that.
A little bit of Spanish. Theoretically I'm supposed to know quite a lot of both Spanish and French, but in reality it's somewhat different
As a Swedish speaker I of course understand Norwegian and Danish well, but I can't speak either language. Though then again, that's not needed as speakers of those languages understand Swedish too.
I also have, oddly enough, quite a good understanding of Dutch, despite never studying either it or German. Medical school might be a good way to learn some Latin too

Just that it's a somewhat narrow scope, to put it mildly.
