Good post. Thats an interesting exercise. 19/20s, 18/20t, but i'm argumentative and disagree with their assessment of one they marked incorrect on the traps; nope, I'm still not doing what they said. Probably makes up for one of the signs I got correct which I used the force to guide me on, since I really can't say I actually saw it when it flickered by.
This would be an interesting weekend test. Have a couple beers, repeat. see score plummet. They'd have to limit the answer time to get the full effect, though.
