<p>Regarding the AMC’s: If there is not a college in your area offering the exam, you can have it proctored at your local library. I registered our homeschool with the AMC folks and they sent all of the testing materials directly to our local library. </p>
<p>Regarding the science Olympiads: I am only familiar with the Chemistry Olympiad. Unlike the AMCs, you can’t register directly as a homeschooler. I needed to find a school in our area that would register my son under its school name. Each school is permitted to send a certain number of participants to the local level; my son was not included in the school’s allotted participants, so it was not difficult for me to find a school to sign him up.</p>
<p>Good luck with your last two years of high school.</p>
