<p>You do not need your school's involvement for USAMTS. Go to their website: <a href="http://www.usamts.org/%5B/url%5D">http://www.usamts.org/</a> and you will get all the info you need. While the competition is done for this school year, you can read about the program and register for their email list.</p>
<p>As far as AMC, you will need to get someone to proctor your exam, and that is probably done most easily through a school sponsor. However, home school students take the exams so there are other methods. The website is <a href="http://www.unl.edu/amc/%5B/url%5D">http://www.unl.edu/amc/</a>. This competition is finishing for this year, but you can learn about the competition and read the rules by reviewing the site.</p>
<p>My son does both of these programs and he really enjoys them. As you will see when you read the websites, they are very different.</p>
<p>Another program you can participate in is Math League. Their website is <a href="http://www.mathleague.com/%5B/url%5D">http://www.mathleague.com/</a>. </p>
<p>I keep thinking of more. Their is another called Mandelbrot and their website is <a href="http://www.mandelbrot.org/%5B/url%5D">http://www.mandelbrot.org/</a>.</p>
<p>I'm sure there are even more programs, but these are a great start.</p>
