From what I've heard from others who have taken the DAT, the sample on the ADA's website is way easier than the real thing. I took that sample test when I began to study and was relieved at first. Then I started getting into Kaplan, the Destroyer, and other practice tests that the people on here say are much more representative of the actual DAT. The ADA's sample seems much more simplistic even just comparing to their outline of topics they say you need to know. It would be nice if they actually correctly represented the level of difficulty on their own website, but I guess it's more of a way to familiarize you with the overall format. And as I have not taken the real DAT yet myself, I am only speculating. I would prepare for a much broader scope and higher level of difficulty than the ADA's sample though....
