Duolingo’s Music and Math Courses
Man, talk about both exciting and frustrating all at once. Duolingo launched both a Math and Music course recently, but it was iOS only, initially, and I use Android. It would come eventually though, and it apparently has, and I missed it, or at least, missed the announcement, if there was one. I have been periodically checking and they were not there until fairly recently.
