CDP Test #1
on Keyholes....questions 4 and 9.
I got those two wrong somehow, but I'm VERY certain that the explanations CDP gives are wrong. Anyone else feel like CDP is wrong on those two questions, or am I taking crazy pills?

funny these are 2 questiosn i got wrong.

but for #4, i wasnt sure i guess its right, but for #9, their explanation is right. u have to look at it standing up, with the longer thinner part being the back piece of the viewpoint they give u, and the diagonal thing closer to u being connected to the thicker part in the answer choice

For #4: The "Back (front)" explanation looks right. The triangle appears slightly bigger in the example but not enough to remove it as the right answer.

For #9: I felt the same way--the "Bottom-Top" explanation looks like the rectangle's diagonal should be extended a bit, filling half of the space left on the edge of the big rectangle. In addition the edge of the big rectangle looks like it should be tapered behind the smaller rectangle.

The real point is that even with the mistakes on the explanation, none of the other choices fit. A, B, D are out obviously. E cannot work because the right corner of the smaller triangle is lower than the left corner in the example. Unfortunately even though it is a miserable problem and should be removed, C is the only viable option.
