Suggestion: grammar reference follow-up.
Hello guys, I'm trying to study German and Duolingo seems to be adding quite a lot to my class studies. What I personally miss, is not only training my weak spots but also pointing me out what they are. here is how I see it: 1) I go through activities, making mistakes and looking for translation of words 2) Duolingo knows more about my mistakes and where I hesitate to input the word without looking at it, or what I haven't heard right. 3) Duoling then analyses my mistakes and other problematic zones and 4) either shows me the grammar (vocabulary) section corresponding to the problem zone, or (even better) sends me an email with those.
Do you like the idea and is it reasonable?
