<p>Due to scheduling conflict, I had to drop the 2nd semester of AP physics which includes electricity and magnetism.. but I still signed up for the AP test. I know that E and M account for 25 percent of the exam per the college board website, but I was wondering If I can with reasonable effort make a 4 on the exam.</p>
<p>There are two DIFFERENT exams. AP Physics Mechanics and AP physics E and M.</p>
<p>I don’t know if you’re signed up for both exams. It sounds like you can get a 5 on the Mechanics AP</p>
<p>I think OP is taking Physics B, not Physics C. Physics B includes both mechanics and E&M on one test.</p>
<p>“With reasonable effort” - you might have a chance if your effort includes studying as much E&M as possible in the remaining week. At least study the basic concepts and equations! Use one of the test prep books for a more concise summary and do a few practice problems to drill the basic stuff into your head.</p>
<p>the curve for a 4 is around a 50 percent right? And yes im taking physics b</p>
<p>Sure you can get a 4 lol. My teacher did just over half of mechanics, all of E/M, and 3/4 of optics, but never did anything else, yet I got a 4. It sort of was a bad year where we got stuck on mech when almost everybody didn’t get it and a bunch of other factors… </p>
<p>You can BS your way with a general understanding of the concepts and knowledge of the formulas on the sheet. There is quite a bit you can derive by just plugging things into the formulas given. For E/M, just cram circuits, the formulas in a little bit of context of when to use them, and learn the right hand rule and how that applies to magnetism…</p>
<p>ok, thanks tangentline</p>
<p>learn the basics, it’ll take an hour or two. Electric fields, voltage, equivalent resistance/voltage/current, coulomb’s law, ohm’s law, etc.</p>
