I am a sophomore and I want to take the DAT at the end of the summer, but I can't find the dates anywhere. Are the tests always on Saturdays like the ACT and SAT? I also have been using Kaplan's DAT prep book, is there another one I should use?
You'd sign up through Prometric's website (http://www.prometric.com/ADA/default.htm) and can pretty much take it any day you want as long as the day is not fully booked
The exam is offered almost everyday and a few times throughout the day, you would register through the ada website, and then check prometric for the testing locations and times available.
