Excellent series to use with a group of adults learning to speak French. HOWEVER, I have not-been ble to track the matching ISBN 2090338546 Adjusted to go with it, only the New Edition is offert by Amazon And They do not match up at all! The whole complex of this series is very well put together and balanced. HOWEVER, the Intermediate Level repeats much of the goal Newbie simply in more depth. The books are suitable for teaching French as A Foreign Language, irrespective of the native language of the student.
