<p>How hard would it be to self-study for Physics C, considering that there's less than three months until the exam? And would it be feasible to take both Mechanics and Electricity/Magnetism or would it be better if I just took one?</p>
<p>I've taken Physics B already and did pretty well in the class (w/ 5 on AP), so I'm wondering if there's a bit of overlap, I guess. At the same time, I've heard that Physics C is very hard.</p>
<p>(Self-studying Physics C this year, with a 5 on self-studied Physics B as background.)</p>
<p>There is overlap. It is challenging (for non-geniuses), but manageable. The difficulty level for Mechanics is a bit higher than that for the B exam, due to increased depth and a more mathy approach, but it’s not really much different. (Dunno about E&M yet; I need to start on that soon…) I don’t suggest you study for more than one exam if you’re starting now, unless you’ve done some physics in between the AP exam and now. If you’re really motivated and can work hard, however, you might be able to do well on both exams. It’s your decision.</p>
