We have just started using the materials. The format in the student books is easy to use and provides additional materials for discussion. The Leaders guide has excellent background material. I especially appreciate the author presenting other resource information than his own. I find that I want to do more study and research than I seem to find time to do. I really did not anticipate Romans to be such an interesting and exciting study. We are looking forward to continuing with the series of materials. It is interesting enough that we have located some CD studies complimentary to the material and will integrate them into our Bible Study time.
