Does someone else have the feeling like Duolingo sometimes updates the course-order and while you get newly sorted in there is some surprise new vocabulary you did not learn before? I am doing Duo for a year and a half, in this time they did some major changes in their Design and learning scheme. So maybe I am just bad at Vocabulary but this really stuck out to me.
Oh okay, I would be happy with some supplementary grammar lessons I guess. I am also annoyed that duo does not give ich habe explicit hints here and I have to research everything by myself.
I guess I will have a look into Busuu, thanks :)
