Steve,
I did not have this experience. Each question on the test was like something I had experienced in the exam simulator. Some questions were (for me) harder than others due to a complex or subtle situation, but that was a matter of degree rather than the nature or topic of the question being a surprise.
I don't know if this answer helps you much, unless you're just looking for some reassurance that the studying you're doing is preparing you sufficiently to take the test.
Best regards,
Tracy
