Thanks everyone for sharing your DCs experiences. We are going into this next year, when all these options open up, so I was curious. It seemed from reading posts here that many math club students do multiple competitions? (ours is only MATHCOUNTS, I believe) -- but I suppose if it is a general math club, then they can participate in various ones throughout the year. This makes sense. For Science Olympiad, efforts are usually geared specifically towards Science Olympiad. That's my take on this now from all of your inputs...
