This free course, Intermediate German: Understanding spoken German, has offered you some support and advice on working with audio-visual materials in German. Do not see this as the end, but rather as a step on the way to working independently with materials to develop your German further. There is so much material that is readily accessible online. Take every opportunity to watch, read and listen. You can listen to German radio, watch soaps and look up things on youtube that interest you. If you are interested in a topic in English, then follow it up with finding more about it in German.
Weiterhin viel Spaβ und viel Erfolg beim Deutsch lernen!
