yeah, I had several "rocks" on the actual DAT... TBH I was completely baffled by the multiple faces/indents/protrusions... I actually never saw a single "rock" example until the test. lol
I actually laughed when I saw that, but I had non-circular rocks if that makes sense. So imagine a rock that is "irregular" with lines all over the top, bottom and sides (indicating which part of the figure is coming out and going in, for example). It's a lot harder to describe now that I think about it.
