I'm pretty sure section 3 was experimental. Form what I understand, every one has the experimental section at the same time. From readomg through postings on some other boars, it sounds like section 3 was it.
I had 2 games sections as well, 3rd and 4th. My 3rd section was pretty easy, had 22 questions. The 4th section was tougher, 23 questions, the first set there was no room for notes/diagrams, there was student/faculty housing, colored pencils, and i think birds. I'm pretty sure this was the real one.
Hope that helps
