I'm pleased to report that all the CDs cover their respective topics thoroughly and accurately. With all the CDs, you can choose to automatically or manually work your way through a main narrated presentation of about 40-50 frames. You'd think that would be too short, but each frame incudes a lot of content, so the presentations really do the job. Not only is there a lot of content in each frame, but there are animations and movies as well. The interactive tests included with each CD are a pleasure to use.
Every interactive module comes with clear instructions on what to do.
The people at Cyber-Ed have obviously gone through the trouble of making varied and interesting tasks for students to complete. There are even more advantages to these CDs. Each one includes excellent test modules that will assess your understanding of the topic. You can tailor the test difficulty somewhat, by changing the amount of response time per question. If this wasn't enough, a wonderful text supplement will accompany your purchase.
