Just a heads up. There are problems on every single PAT practice test out there. If you rarely catch them then keep practicing 'cause every company (Kaplan, Topscore, Achiever, CDP) has errors and needs to edit their materials. But the good news is this prepares you well for the real DAT because when I took it on 8/31 (PAT24 %99.5)there were two pattern folding questions which each had multiple correct answers. I marked them, came back and spent 5 minutes on each- and I am %100 sure that each of the 2 showed the correct shape twice- from different positions. So, there is definitely an aspect of luck on the DAT in regards to what questions you get- just do your best!
