Yes, I do appreciate the discussions (and the input of moderators) very much. I am glad they are part of the site as well.
I'm not going to lie, folks. It's going to take a while. You'll forget a lot of stuff, but you'll revisit them again later and remember. The best way to remember this stuff, though, is by understanding it. It took me six months for me to get to where I am now, but doing it on an everyday basis will lead to a greater understanding of the language as a whole. Especially if you do a little research elsewhere like at german.about.com (which can explain word order very well), online German dictionaries (for quickly checking alternate meanings of certain vocabulary words that may not be covered by the definitions on Duolingo, I recommend dict.cc and linguee.de/deutsch-englisch), and German blogs (which can be a great help in understanding modal particles). It also helps to know somebody who is a native German who can explain some stuff to you (which I do, and I do my best to relay what she said over here.)
I only JUST finally understood German subordinate clause word order last week. It'll be frustrating, but keep at it and you'll get there.
