<p>There are a few people that I know of who are math/CS double-majors. However, you probably don’t know what a math major at Caltech entails- I can guarantee it’s almost nothing like high school math you have seen so far. I would recommend coming for PFW and talking to people who are math majors and seeing if you really want to do a math/cs double-major.</p>
<p>It’s not necessarily unproductive to split your time between the two, but the reality is that there aren’t that many people who actually like both math and CS.</p>
