<p>If you are looking into chemical engineering you will take physics and chemistry. So it really doesn’t matter. However, if I were you I would take AP CHem. No decent engineering school would ever give credit for AP Physics B. It isn’t calculus based. AP Physics B mildly touches Physics I (Mechanics), Physics II(Electricity & Magnetism) and Physics III (vibrations and optics). Just take AP Chem, i don’t care how hard your AP Physics B course is.
