I also couldn't figure out what they were looking for on the first afternoon problem. It's at least comforting to my ego to know that I'm not the only one. I feel fairly confident on the other three afternoon problems.
First time vertical and lateral exams. I have to say the Friday morning exam was much tougher than I expected, much tougher than the practice exam and I ran out of time and had to guess blindly on 9 problems. The afternoon seemed pretty straight forward and I think I'll do well on each of them...
