Table of reference
Is there anywhere in duolingo a table of all the articles and the cases? some times I have doubts and I dont even know what to search.... I am interested in articles and pronoms...
I think Duolingo's approach is to teach German by repeated correction (as natve G. children learn it) rather than as foreigners learn it by attending class and memorizing tables of rules - cases, endings, etc. However, adult students don't have years and years to learn a language as children do. Therefore, I'd recommend "Cochran's German Review Grammar" as a very good source of information.
