Well, there are two versions of the test (A and B), the four sections that were present in both tests are the real ones, obviously. We found out which sections were experimental about 3min after leaving the room. Everyone remembered some of the questions from each section.
Thus, those of us who has 2 games sections told the other people which RC section was "real", and vice versa, they told us which LG section was real.
And good luck to all of you.
