If you took the DAT, you know how taking a computer based exam should be. As for content, whatever you see in old exams and study packets should get you well aquainted. Since you are 2 weeks away from it, I'm assuming that you don't need to be spoon fed anything, and are just looking for reassurance. Either way, it's not as bad as everyone says. Sure, you'll be yapping about the experience for a couple weeks after, but then you'll quickly realize it wasn't all that big of a deal.
Also, count on scoring about 5-10 points less than the released exams prior to 2000. The newer Part I questions are a bit tougher.
