I took the DAT last week and scored a 25 PAT. Personally, I think the angles were easier on the actual exam, and the choices were easier typically. For example, in CDP, they would always have 1-2-3-4 or 1-3-2-4, with 2 and 3 being almost identical. This didn't happen as often on the actual test. I didn't spend much time on this section, either you can tell right away or you should make the best guess and move on to other sections where you know you'll get questions right. On CDP I probably averaged between 60-80% right on angles. The only strategies I used were finding the largest and smallest angles first, then using the laptop technique (which is the most opened/closed laptop) for the middle two.
