<p>Just like the title says, except I probably won't add one until after I take some courses there. How difficult is it to add a second major?</p>
<p>To add a double major you must meet your new major's change of major requirement. You can see those here:</p>

<p>As long as you meet the criteria and you do it relatively early (i.e. freshman or sophomore year rather than during your senior year), it is relatively easy and painless.</p>
