As far as tips and tricks go, Topscore also comes with this 100 page study guide thing that gives plenty of goodies for PAT, scratch paper setup, etc. Topscore has been invaluable for all sorts of things and even if you do end up taking the Kaplan course you really oughta get it. I would say the same for DAT Achiever but... they only let you take the tests once and then you can only review it. Topscore lets you retake it as many times as you want. I take the DAT tommorrow so I will tell you then if I wish I had taken Kaplan or not, but when it comes down to it, I think the best thing is to study on your own and work practice problems and stuff.
