<p>There are the math programs like PROMYS(<a href=“http://www.promys.org/”>What We Do – PROMYS | Program in Mathematics for Young Scientists). Those accept students your age. There’s also COSMOS(<a href=“https://cosmos-ucop.ucdavis.edu/”>Page Not Found - COSMOS Platform), but since you probably don’t live in California you might not want to apply. Hey, how about summer@USC(<a href=“http://summer.usc.edu/index.shtml”>Summer Programs Absence Request Forms | USC Pre-College)? That’s a good one!</p>
