Repeated sentences driving me crazy!
I'm working on Japanese, French, and German. In all three languages, occasionally Duolingo will offer me the same sentence (or up to three sentences) over and over again. From the thumbnails at on the lesson-choosing page, I can see that there is material that is not being covered. Sometimes, redoing the lesson will fix the problem, but sometimes I will still get the same sentences! I love Duolingo but I wish they would fix this , if only to make sure that all the material gets covered.
