You ask a very good question and I'm sorry to have to tell you they mix up the order of the questions. You could have a question from subelement 7, one from subelement 9, another from subelement 3, and so on all the way through the test.
One way to mitigate this (apart from knowing your stuff, that is

is to read the test through thoroughly before you make a mark on the answer sheet. That way if you can find a couple of questions whose answers relate to one another, you can use that to your advantage.
Oh, and by the way, don't count on the answers for a particular question being presented in the same order they are in the pool, either.
One of the online practice tests (I think it's the one from the WVARA) does this sort of mixing up. The others don't, probably because it's easier to write an online test that way, but I think the mixing up is better preparation for the test.
