I didn't find the audio CDs particularly useful. It is hard to learn a second language without practicing with others, and if you are taking a class the audio CD's are a bit redundant, although they my offer some practice to those who need plenty of repetition.
This was my textbook for my college French. I didn't think it was that good, but I supplemented my studies with some other store-bought non-textbook French books that helped a lot.
