I don't know! That passage was weird! Neutrons maybe? No idea, I remember putting that for something. Most of it was blocked out of my mind. I thought PS was pretty hard. I thought verbal was easier than practice tests (5r and 6r). I thought bio seemed too easy, probably screwed up. A lot of organic, but the bio parts seemed pretty simple. Finished early which I never do. What did you guys think in general, especially bio?
