<p>If you’re not in the IB Diploma, do the AP BC class.</p>
<p>But if you have a firm grounding in math, which Math HL helps you with, the BC test should require less than a week of review/additional self-study.</p>
<p>If you take IB Math HL, you should be able to take both the IB exam and the AP Calc BC exam with minimal extra studying. Or at least, that’s what I have heard from my teacher and friends who are in IB Math HL. I am currently taking IB Calc SL, so the same would apply for me except with AP Calc AB.</p>
