<p>Stanford’s HSSC costs much more than EPGY. Don’t bother with that or similar programs (i.e. Harvard SSP).</p>
<p>For math, try AwesomeMath/AMSP (if you like competitions; I went here and it lived up to its name), Ross, PROMYS (if you like spending ***loads of time doing deep number theory stuff), HCSSiM, or Mathcamp (if you like varied programs in theoretical math).</p>
<p>For science, all I have knowledge of are [Iowa</a> SSTP](<a href=“http://www.education.uiowa.edu/belinblank/old/summer/programs/9-11/sstp/eligibility.asp]Iowa”>http://www.education.uiowa.edu/belinblank/old/summer/programs/9-11/sstp/eligibility.asp), [url=<a href=“http://www.cpet.ufl.edu/sstp/default.html]UF-SSTP[/url”>http://www.cpet.ufl.edu/sstp/default.html]UF-SSTP[/url</a>] (both research programs), and SSP. (The non-Harvard one.)</p>
<p>No clue about social studies.</p>
<p>As for admissions, I don’t know too much about the selectivity of the science programs. All of the math programs have a few (generally about 10) hard-ish problems for you to solve and submit solutions for along with your application (which will require essay-like writing). I don’t know how good you are, since you don’t have an AMC score or anything, but from experience, you should be fine for at least AMSP as long as you don’t really suck.</p>
