Hello Adrienn! Norwegians are very kind people and know English at a high level. I think if you start speaking with them using vocabulary, they will switch to English in order to help you feel comfortable :) So, it might not be easy to find some challenge, learning this language. And challenges make us to progress... It may probably have sense and may increase motivation to learn it if you want to study in Norway at a program in Norwegian language. Then you need to pass an exam and get B2 level, if I am not mistaken. So you can just find some resources for exam preparation and learn with them. Even if you are not going to study there, an additional language certificate would make your CV look better anyway...

'What If you learn a language which doesn't have a lot of speaker, resources and hard to get in touch with natives?'

Hello, Adrienn! I'm looking for people who also learn Norwegian, but they are not native speakers. The main thing is to learn to speak Norwegian. And the resources for learning Norwegian are enough for me.
