Hi, I'm curious since many on this forum seem to have the experience with competitions....

If math and science competition teams are offered at your schools, (ex. MathCounts, Science Olympiad etc) and your kids' schedule allows it, are kids able to do both or do kids start to "specialize" in math competitions vs. science competitions?

Also, I see many interesting on-line classes offered to prepare for Math Olympiad, AMC, Mathcounts etc. at AoPS etc. Are these course only for kids who definitely intend to compete, or can kids who are just interested in building problem-solving skills benefit from them as well?

thank you.
