I'm horrible at the PAT section...so I'm not one to offer any advice, but here's what I do. For the angles, I try to compare them to 90 or 45 degrees to evaluate a rough angle. For the hole punches, you can do a couple of things:
1. The number of holes will be the same as the number of layers of paper through which it is punched
2. Check the symmetry of the fold
3. If a punch is on the perimeter of the square, then check for a hole in the perimeter of the square and the same thing goes for core punches. I can usually eliminate a couple of the wrong answer choices.
If you find any tips/tricks, please let me know!
