In order to answer this truly responsibly, “The Dean” would need to see your overall transcript (all the classes you’ve taken so far and the grades you’ve earned) and also have a rough idea of the colleges you want to attend.
However, responding in a vacuum as I am, my reply (unfortunately) is that you should go with the physics + one AP history class … if you’re aiming for highly selective colleges. If, however, your top-choice schools are those that accept at least as many applicants as they reject (and if you think you’re a reasonably strong candidate for each) and if you’ve taken a lab science every year so far, then follow your heart and opt for the double history. Also, if your senior course line-up includes another heavy-hitter quantitative course (I have AP Calc in mind), then you might dump the physics (again, depending on the other sciences on your transcript). What you want to avoid is a course roster that’s entirely skewed toward humanities with no challenging math or science on it at all, even if it does include an extra AP.
