If your interest is in an evaluation copy of CyberRat, unfortunately it is not a downloadable product. We are happy to ship potential adopting instructors a complimentary copy of this CD/Internet Hybrid, which you may then register with us. For details on how to order and register for a complimentary copy of CyberRat, CLICK HERE.

To fully appreciate how our Adaptive Instructional Textbook system works and to use it as a fully certified "Student", potential Textbook Adopters and Serious Evaluators are encouraged to register as "students" in our special "Evaluation Course's Visitor Section" through our separate registration system accessed by clicking the line below.

This will give you complete access to tutoring for all topics and certification testing for all chapters. It will also keep your user history up-to-date so the artificial intelligence engine can do its work properly to adjust your services as your performance shifts from session to session.

However, using our Software Download page without registration will allow anyone to obtain a free copy of our complete textbook Psychology: Exploring Behavior", by R. A. Kasschau, as pdf files and/or as an on-line electronic adaptive instructional and testing system. In this later case, you download our custom browser to interact with our servers. However, without any form of registration with us, this electronic version is somewhat limited in its services. It will only allow you to use the system as a Visitor, which includes the following limitations:

1. Adaptive Instructional Tutoring services are limited to one conceptual kernel, or topic.

2. Mastery Certification Testing services are limited to one Chapter of the textbook.

3. No historical data on any user is maintained, which severly limits the artificial intelligence engine's ability to deliver adaptive tutoring and adaptive testing services beyond one session.
