<p>Yeah, if I were you I would sign up for math, econ <em>and</em> physics. Math and physics are pre-med, so your parents should be fine with it.</p>
<p>Chances are you will change your mind about your major(s) later on once you start taking classes. I started college with the intention of double-majoring in math and econ. One year later I have abandoned all econ plans and I am anticipating a math major with a minor in computer science.</p>
