I am swedish myself and as such I know my own language...
Sure?
Acc. some german Dudes in an unlighted aviation hazard I got to proof that I can speak german (German national, born in Germany to German parents)...despite the fact that I own a German radio certificate that states that I can do radio in German and English. Following the English level 4/5/6 joke a few years ago...
Sorry for OffT.
