Starting to Learn German

Well I've started to learn German. I signed up for a class and paid for it. Still have to buy some of the books though. Went to the first hour of class, but was kinda lost, since I joined a course where the people have already started a month ago, so have some catching up to do. Before starting I knew just how to say "Good day", "Good bye" and count to 10. German seems like a pretty hard language to start with...
