<p>Ok so I know about the USABO (biology), USAPO (physics), and AMC 12. I'm going to take the AMC 12 in february, but when are the USABO/USAPO tests? My school doesn't offer those, so how should I take them? and who should I talk to? Thanks!</p>
<p>for USABO go Here: USABO</a> index page</p>
<p>it tells you everything you need to know</p>
<p>the olympiads are pretty accessible if you look around. i know the amc website lists public places where it can be taken (like colleges and stuff). usabo is a school registration fee of $75? so if your school doesnt offer it but you know a teacher who wouldnt mind proctoring the test to you, you could just offer to front the cost yourself, or find a nearby school does offer it. not sure about usapho. usnco is done through your local acs section. usaco is year round online submissions, im pretty sure. i dont know of any other olympiads lol.</p>
