Generally, this course is quite good, but it is best used when it forms the centrepiece of a proper french class; it depends quite heavily on authentic conversations from native speakers, and some of them are spoken very fast with a lot of "distortion" due to local dialect. However, there are several exercises that have no associated transcripts (although they do have answers to questions about the conversation in the exercise). This can be extremely annoying if you are trying to use the book independently by yourself.
