<p>You need to sign up on a team. When you inquire how to sign up for the team, they will let you know whether or not you can. I think you cannot, but wouldn’t it be so cool? I am assuming you have been to Ross? If you have nothing better going on this summer, you should so totally do it- 6 weeks at Ohio State University, first-years work on number theory; and I predict that you would absolutely love it (though you have probably already gone?).</p>
<p>You do know that the first round of USAMTS is currently open, don’t you, and that it is an “alternate” pathway to USAMO.</p>
<p>If you love competitions, you could compete on “Who wants to be a Mathematician” held at AMS meetings. Look it up on YouTube. I love to watch Evan O’Dorney.</p>
