Tag,
I have been working my way through the audio courses as I walk to & from work, but also separately through the other material online.
I notice in several of the lessons, there are references made to learning more in the written materials (eg when talking about the split words, as in "halten bald en" in lesson 2.2), but when I go to look at this material, the only written notes are the literal text of the actual conversation. An improvement would be to indclude (at the very least) a reference to the grammar lesson in which one could learn more about the referenced concept (I haven't yet found any more written about "enhalten"), and better would be a commentary for the introduced concepts with the lesson text.
I also note that in several of the lessons, other words are mentioned (eg die Sauna, etc), but that these are not included in the texts that accompany the lessons. Again, it would be helpful if the text that accompanies the audio also included a list of these extra words.
Also, some of the quizzes in the audio lessons make reference to conceps that had not been disucssed in the audio lesson (eg how to say "What would you like?" in a formal way - when the lesson has only used an informal form of the verb). At the time of this question, there was no information on formation of verbs or link to that information.
The format of the 6-day sample lessons was great with the supporting material providing follow-up discussion of the concepts in the audio lesson that had been presented the previous day (not just a transcript of the discussion), and I found this methodology quite helpful. I was a little disappointed that this structure was not continued in the full course.
I understand that the grammar lessons (language and culture) are presented separately from the Interactive Audio course. While the structure of the course would seem to imply that one works through the lessons in a chronological order (doing first all the audio in a section, and then all the Language & Culture), I have seen comments suggesting that one interleaves these different parts of the course - and recognise doing so may address some of the above, but probably not in all cases.
Sorry if the above comments are a little negative. The above issues aside, I am enjoying the course, and particularly like the friendly tone of the audio and the way one feels like part of the conversation ... I have even found myself laughing at the conversation on occasion.

I enjoyed Rocket German Premium very much. After completing all 5 levels of German offered by Rosetta Stone, I was disappointed that I had a nice vocabulary and I could read and understand quite a bit, but was unable to carry on even a simple conversation in German. The extra vocabulary was especially helpful when I could review it in written form.
Now I am working on Rocket German Premium Plus and I see that the extra vocabulary is not included in the written materials for this part of the course or for Rocket German Platinum. Without the written materials, the extra vocabulary given in the interactive audio is almost worthless. The speakers give you the examples once, very quickly, and then move on, giving you no time at all to learn these phrases. I hope that this will be changed soon, and that we will have access to all the extra vocabulary in written form.
One other improvement I would like to see is for all the written materials to be available in PDF format. Currently, this option is available only in the Language and Culture sections.
Overall, I think this is a great way to practice and learn German. I have recommended it to my friends, and hope you will continue to work on improving it!
