<p>IB SL or HL? It appears that IB HL English A1 or A2 will cover both halves of R&C. IB HL Math may cover Math 1A and 1B, but check with the Math department to be sure.</p>
<p>However, even if your IB is only SL, then it should be doable, since the long chain of prerequisites for math is:</p>
<p>1A -> 1B -> 53,54,55 -> 104,110,113,* -> other upper division Math courses</p>
<ul>
<li>A few other upper division Math courses courses require just 53, 54, and/or 55, but they are not crucial prerequisites for more upper division Math courses.</li>
</ul>
<p>This chain is only 5 semesters long, but you will have 6 semesters to complete all of the degree requirements. Of course, this would mean taking 20 units per semester (including breadth and other electives), though this is more doable as a math major than many other majors, since math courses tend not to be very time consuming (the way lab science and engineering courses, art studio courses, CS courses with programming, etc. can be).</p>
<p>But if you do get useful credit out of IB HL, including Math 1A and 1B, then you will shorten the prerequisite chain to 3 semesters, and need to take fewer total units to graduates, so it may be possible to graduate in even fewer than 6 semesters.</p>
<p>Whether you actually want to graduate as quickly as possible is another matter. If you are a full pay OOS or international student, or need to take significant loans to attend, there is certainly a financial incentive to schedule aggressively for quick graduation. But, as the previous poster said, there are other advantages to taking an extra semester. One advantage not mentioned is that an extra semester may make it easier to do both “pure” math courses for graduate school preparation, while also taking courses in areas where math is applied (e.g. statistics, computer science, economics/finance) to improve job and career prospects for internships and if you do not go to graduate school.</p>
