angles- you will end up getting it down to 50/50 chance of getting it right, just prey you get the right one.
hole punching- are a piece of cake. Just practice with paper if you cant imagine folding things in your head. Always go step by step seeing where the holes end up and you will end up at the right answer.
counting- Make sure you look over each question on here twice chances are you'll miss a square. Also watch out for hidden cubes that are partially visible.
Best advice is practice, practice, practice. I actually started studying for this section before everything else 1. because I was too lazy to study sciences, and 2. because it looked like fun. If you get good at these, this part of the test will seem like a break rather than a section. Good luck and do your best!
