I think the CDs of this series very helpful for lesson preparation. There are many many worksheets and an appealing variety of methods (games, assigning tasks, text / image analysis, etc.) You can see the AB arbitrarily change and everything zoom in / out smoothly. Solutions are available. There are many images that you can print them on film and use during the lesson. I also like to print two pages on one side, then saves copies. With compatibility mode the programs are running (whether old or new 2.4 Version 1.0) bit on my Win7 64 machine since I was skeptical at first. On the previous PC it runs anyway. Conclusion: recommendable.
