<p>To use UC Berkeley as an example:</p>
<p>Pure Math: 5 freshman/sophomore Math courses, 8 junior/senior Math courses (total 13)
Computer Science: 3 freshman/sophomore CS courses, 1 electronics course, 6-7 junior/senior CS courses (math courses overlap) (total 10-11)
Breadth: 2 reading/writing courses, 4-6 other breadth courses not fulfilled by the majors (total 6-8)</p>
<p>So that is a total of 29-32 courses (a typical student takes about 32 courses over 8 semesters), so not a lot of breathing room. However, many Math majors come in with 5 on AP Calculus BC, so that removes the 2 freshman calculus courses, for a revised total of 27-30 courses. AP English credit may fulfill 1-2 of the reading/writing courses as well.</p>
<p>If actuarial or finance interests you, you probably would want to add about 3 Economics/Finance courses and 2 Statistics courses. That would mean 32-35 courses, requiring some overload semesters (which is doable if one does not put too many heavy computer programming courses together).</p>
<p>You could get a bit more breathing room by downgrading the CS from a major to a minor, taking only 3-4 junior/senior level CS courses (algorithms / complexity, operating systems, networks, and software engineering are probably the highest value if you are looking at industry software development jobs and careers) and not taking the electronics course, for a total of 6-7 instead of 10-11 courses – i.e. 4 fewer courses. That would make the total 28-31 courses, assuming starting with a 5 on AP Calculus BC.</p>
<p>Changing the Pure Math to Applied Math would effectively allow replacing 3 of the junior/senior level Math courses with Math-heavy courses from other subjects like Computer Science, Statistics, and Economics.</p>
