Gather a group of friends and go get the language skills you need, once and for all. Or book private tutoring for your particular needs. Why should you settle for a half-decent language? Let's meet in a pleasant environment in central Östersund (next to the bus station) and do what it takes to make your Swedish just as good as you want it to be. It's never too late!
Don't live in Jämtland? Too bad, but we can meet online too. Or do you want me to come to you?
