Does duolingo relate same language courses of different language base?
I would like to know if duolingo relate and analyses my learning of german for english speakers with german for italian speakers for example.
When you flip between your base languages you see the stats for languages you are learning from that language. It is just like you were learning from different accounts, there is no way to compare German from English and German from French on one page, no way to see them next to each other without switching the base language. Hope that answers your question.
