Prior to buying these CDs, my husband and I used the 2-CD set, "Speaking French with Michel Thomas." We learned a lot quickly from those CDs, but wanted to learn more. So, we purchased the Instant Immersion French set. This has to be one of the worst purchases I have ever made! It is very difficult to determine what the people on the CD are saying, and the tasks are unclear. There is no guide book to help you along.I'm going to purchase the full Michel Thomas set now, and highly recommend his method of teaching over this set of CDs.
