Keyholes Rules

Hi,

I know this may be a dumb question, but I am having trouble and need help with an important detail of the PAT apertures (keyholes) section as I prepare for my exam.

My strategy is to emply my knowledge of the rules to eliminate incorrect answer choices. But, one of the rules is unclear to me. The rule that says the correct keyhole is drawn to the same SCALE as the object confuses me, because it seems to, at times, contradict the rule that says the silhouette of the object must be exactly the same as the correct answer choice so the object can pass through.

What I want to know is, if a keyhole can be too small, can it also be too big even if the shape is correct? Or, is too big okay as long as the object passes through?? Please help! Thanks!

I am surprised to see nobody answered and yet it's understandable because there is no definitive guide on this topic. I've done topscore, achiever, crack the dat and seen many problems contradicting the rules. Tricky ones I've seen them all. A good news is that the keyhole problems on the ACTUAL dat are not that tricky but quite straightforward. So take it easy.

[Edit] When you do the practice problems, pay attention to the details like angles, shade of protruded part and etc. Too large or small scales are probably wrong choices. See if there is any alternative answer.

A key hole can be too small or too big. If you look at PAT Achiever (I still can't break a 18 on that freaking thing) they are constantly throwing right projects at you that are a little bit too small or too big to be the answer. This usually happens with the top or bottom projections.
