I got a 98+ percentile on the PAT
I bought the 10 test Crack the PAT and did everything. The biggest hurdle with the PAT is timing, and if you're not practicing with a timer you're going to have trouble on the DAT.
For angles, I was first having alot of trouble with them, I went to the eye doctor and it turns out I actually needed glasses. The angles on the DAT were more obvious than on Crack the PAT, so that was a help. As for solving them, I found imagining I was skiing down a hill(side of the angle). From that I'd determine which "hill" was steeper. If it means you need to tilt your head to line it up, do it. Heck, I even got out of my chair during the DAT to solve a couple. On the DAT, you'll also be able to use process of elimination on some of the questions. I either found the largest or smallest angle, which are usually obvious, and from there I'd compare the angles based on the answer choices.
For Hole Punching. First create a 4 X 4 Grid. This grid will correspond to the potential areas on the paper a hole can be made. Start at the last figure given and work backwards. Put an X in whatever box has a hole punch, and use the folds as lines of symmetry to translate the additional holes.
