<p>So I JUST joined CC after lurking around here for days, and I'm kind of interested in the Siemens Competition, but it seems REALLY tough. Like, I don't understand any of the topics I've read about...or even register what they COULD mean for that matter. So for anyone who has done it before, what kind of science/math background did you have? And how did you go about tackling it? Thanks in advance!</p>
