<p>IB math HL is often considered slightly more rigorous than AP calculus BC; both are often given credit for a year of freshman calculus in college. AP calculus AB is less rigorous and is usually given credit for only the first semester of freshman calculus in college. Since you are two grade levels ahead in math and in an honors course, you should be a top student in math who should be able to handle IB math HL or AP calculus BC.</p>
<p>See above discussion for the difference between AP physics B and C. For whatever reason, IB physics does not seem to be very well respected compared to other IB subjects, or AP physics.</p>
