<p>I would prioritize C++ first as that seems to be the predominant language for CS classes, but CS majors in general should be comfortable with at least a few languages.</p>
<p>A double major would definitely be possible as CS at UCD is not as unit-heavy as it is in some of the other UCs (although one is more than welcome to go far beyond the minimum requirements; it’s simply nice to have the option to pursue other interests).</p>
<p>I would advise him to take the multivariate calculus exam because as of now, CS has a lower-division computational statistics requirement (STA 32) that cannot be fulfilled by AP Statistics (which satisfies STA 13).</p>
