I have a few questions…

<p>Hi, I'm new here. I have a few questions.</p>

<p>Are there many other high school freshman on this site?</p>

<p>And also, as a freshman, I am not currently doing any extra-curricular activities. How will this affect my chances when I am applying for colleges? I am hoping to get into a UC/private school, and I read a lot about how extra-curricular activities are important in applying for these types of colleges. The problem is that, the only interest I have is in math and I don't know what kind of extra-curricular activities that are related to math are available.</p>
