The AMC actually does a pretty good job covering all topics. This one was a bit light on probability and combinatorics (IIRCjust 2 problems, and both were easy). This one also seemed a bit heavier than usual on "set theory-ish" stuff. I can't really explain it any better; there were a bunch of tough problems involving finding the highest or lowest values a given set of rules will hold. The geometry problems were not particularly advanced, just long, leading to a high probablity of making a minor error.

Just know basic geometry rules, and basic algebra. That will get you through at least problem 15. The last 10 are all experience and finding different ways of thinking about things.
