I don't think I saw anyone identify what kind of games were on experimental. Real were linear + one in/out. What kind of games did you have? Anything tricky or noteworthy about them?
There was one about stone and mulch with trucks that I found to be one of the hardest (if not the hardest) game I have ever seen. I had no idea how to diagram it, though now I seem to have a better grasp on it. I remember the game verbatim, so as I was driving home today, I was making hypotheticals in my head. I feel sorry for the person that has to do that game for the real test... On that experimental LG section I believe I filled in B from 17-23 because I was too busy trying to understand the stone and mulch trucks. It was a sequencing game with some sort of third entity to keep track of as you switched from stone and mulch; what a nightmare.
Another one of the sequencing games on the exp LG had a very, very awkwardly worded question that gave a partial list of the sequencing and asked you which one would work given a certain rule setup in the question stem. It was weird because you could add the variables in between or to the beginning or end of the sequence. Between these two things, while taking the test I was almost certain that was experimental (and alas, I was right).
1x I can't remember
I had the EXACT same experience. I spent so much time with my M's and S's (mulch/stone) that I had to fill in EIGHT guesses at the last minute. I felt that section had to be experimental and that two of those questions should be thrown out. I remember with the stone/mulch question, going through the answer choices for one of the questions and realizing they all worked except for one of them. I expected the question to read "all could be true EXCEPT"...but it was "which could be true". Made no sense!
