Is 1986 recent? I didn't look into it at all, no prep--I was an art major working on my show. I don't remember any math at all, and I'm so poor at math I couldn't understand my scores until I got a fellowship based on them, which I took to be a good thing. There were lots of symbolic logic problems in story form. If three knights are travelling and knight A will not ride with knight C, etc.

I remember some texts that lead one into symbolic logic by way of verbal logic--I think that might really help. I took logic because I was allowed to substitute it for math, at U. of Kentucky. Good luck, don't be nervous. I always do better by taking a casual attitude.
