cem nvr "pictures"

[southbucks3]

Could somebody please help me clarify exactly what type these are? I am trying to work out my son's re-mark and analysis from bucks and he did very well on these compared to sequences, as he said the questions were less cluttered and he felt under less pressure to go fast. I am wondering if they are in fact much easier than sequences? He always did extremely well in all sorts in practice nvr tests, but I believe ramping the speed up panicked him on the sequence questions, and he then started losing his place on the multi choice sheet as well.
Answers very much appreciated, as "pictures" does not mean a lot to me, and he gets visibly upset if I quiz him on the test itself.
