<p>Where were you planning on staying if you did Cornell summer session? Relatives? My favorite parts of summer college were the kids I met and the freedoms of college dorm life. You'd be missing out a lot if you didn't get that experience.</p>
<p>Do you get along well with your math teachers? See if one of them that knows how strong you are in math can give you some advice on possible ways to accelerate. If you're "stuck" in a slow moving class, keep challenging yourself. You might want to focus on the AMC/AIME tests ( <a href="http://www.unl.edu/amc/%5B/url%5D">http://www.unl.edu/amc/</a> ). There are some materials at <a href="http://www.artofproblemsolving.com%5B/url%5D">http://www.artofproblemsolving.com</a> that I've heard are fantastic.</p>
