<p>How do you prepare for USAPHO? I'm currently a sophomore self studying AP Physics B (school doesn't let you take it until junior year), so I won't be taking AP Physics C until senior year. I want to qualify for USAPHO junior year, so what can I do to prepare? I'm currently taking precalculus.</p>
