<p>If you like math, take the AMCs. If your school doesn’t offer it, start it. </p>

Also, Caltech recommends that you take AP Calculus BC (not AB), preferably before senior year. Since your school doesn’t offer AP Chemistry/AP Physics C, you definitely want to take those junior year (and get 5’s).</p>
