Dear missionmba,
I apologize for any inconvenience this may have caused you. Your satisfaction with our products is very important to us!
The problem you experienced is a very rare software issue with the CD. As you know, the difficulty of the questions given in a CAT is based on your performance on the previous question. The way that the CAT software on the CD works is that it grabs items from a pool, which contains questions of various difficulty levels. What happened is that you simply went through all the questions of a particular difficulty in the question pool. The software didn’t have any questions left in that difficultly level for the third and fourth tests, and therefore, would not be able to provide you with valid/accurate test scores.
As compensation for the troubles you've had with the CD, I'd like to provide you with special access to additional GMAT CATs online. If you are interested, please let me know via a personal message (pm). I'd be happy to reply directly to you with that information.
I apologize again for any inconvenience you may have experienced, and wish you the best of luck on your exam!
Sincerely,
Monica P. Lugo
