I think knowing xor is the trick because once you recognize it, the first half or so of the test becomes a bunch of questions that are exactly the same. It would be one thing if I thought they were equally easy (then I could imagine that I was just saturating them with my Giant Brain(tm)) but for them to be absolutely identical, I think, shows that the test isn't working anymore.
