well you have to find what you find most comfortable with. What I do is I downloaded all the full audio lessons to my mp3. I love them cause it does give you a very good sense of the conversation, they explain every piece of the sentence and is easy to remember and understand the structure. They are actually quite fun so I listen to them every morning while I work out at the gym. I do look a bit crazy talking to myself while trying to repeat what I hear, but everybody now know I am learning German so everybody respects that ;) ... Anyways, after listening a couple of lessons (sometimes a couple of times each) at night I go to my computer and repeat the entire lesson but now with the written material. I do the quiz and rate how I pronounce things. Once I feel I got it, I move on to the next lesson. I usually go from 2 to 4 lessons a day, depends of the time I have and my mood. I do have to admit it took me a while to finish cause I was a slacker for a few months but once I put some effort, I pretty much finished in a month. I have finished the basic course, but I still feel I have to keep practicing a few more things.
