> Because their 'preparations' usually suck. I think we're much better off now, thanks to Art of Problem Solving's Alcumus, Richard Rusczyk, all the top-tier video lessons out there, etc-- along with just things like being able to hand out Khan practice for general math topics. We're getting much better at teaching top students how to solve hard problems (and, as a result, the AMC8/10/12, AIME, Olympiads, MathCounts, et al... are getting much harder-- these days if you want to prepare for the AMC8 you should be studying old AMC10 problems). The same can't be said about overall societal performance in teaching the entire population.
