Keyhole:
You really do have to look at all the answers cause they can get tricky. Don't eliminate answers too quickly in this section since a simple turn of the piece could make it fit in a hold that looks totally wrong
Top-Front-End:
You can usually eliminate 2 choices very quickly cause a piece of the puzzle is inverted or an obvious cone is made out as a column in the answer, etc. Usually you then have to count lines in the other two options to see whether a dotted line or solid line should or shouldn't be in the answer.
Angles:
Just got to eye. If I see two really close angle, I put my thumbs over both of them very close to the angle and then I can usually tell from these smaller lines if the angles is bigger or smaller.
Hole Punch:
Study with Achiever...it's the same. I draw a giant 4x4 square on a piece of paper and when I get a harder folding pattern, I work from the hole punch backwards and make dots on the paper as I go to determine where a hole will be or if the hole moves as the paper unfolds
Cubes:
I count and list all the cubes in a figure before I start. (like)
Figure 1
5 5 5
4 4 4 4 4
3 3 3
2 2 2 2 2 2 2
1 1
0
then I answer the questions and start again with the next figure.
Folding:
for the easy ones...eliminate fast and keep going
for the hareder ones, take a few seconds to orient the piece in your mind and where all the shaded and unshaded parts are. Sometimes with simpler shapes that have shading, I even draw a sketch, but then it's just a bunch of looking and eliminating.
