Anyone here have any experience with Kaplan Professional online?

I logged onto the Kaplan Professional website to poke around and get familiar with their online system and I ran into a brick wall; I just don't understand how this system works. I taking the Real Estate Brokers course and they shipped me the self study books and I was under the impression that I would be able to log-on and take the final test for each subject online. However, I poked around and I can't seem to figure out how to get to the online test portion?
