The idea of this subforum "Swedish fromEnglish" is tohelp you getting fluent in Swedish.
Sweden is to my knowledge the country with the best online material, as well as schools, to accomodate a large numer of mmigrants, and to allow them to learn the language and integrate in their new habitat.
Here is a graph of the number of immigrants to Sweden. (source: statista) Many of them learning Swedish also on Duolingo. The estimate is between 20.000 to 80.000 people actively learning Swedish, many others doing this via (evening-)schools too.
