<p>I’m straight A student, 2400, and taking Calc BC and Chem as well as Physics C. And I have to say that Physics C has to be harder than all my classes combined (AB was a joke, I slept every single class and received highest grade in all the periods). It’s extremely calculus intensive, and the problems are not so much knowing how to do algebra (which you learn in math) but tackling and setting up equations for the problem. Unless you are a master of brain gymnastics, I advise against taking this course. If you do, I suggest that you stick to Physics C Mechanics. E/M is murder on the mind and the little magnetism that we have done so far, I opted to just fail the tests rather than wreak havoc on my mind.</p>
<p>go for it. AP tests are, by their very nature, jokes. There’s only so many important concepts to test you over.</p>
<p>As long as you buy a guidebook and are well-aware of what you need to know, (and how much you actually do), you’ll be fine - getting 5’s should be cake.</p>
<p>On the other hand, you should consider whether or not it is the best decision. For Calc, if you are a math person you should go for it without a second thought - you won’t lost much from missing out on the experience. For Chem and Physics, I think knowing enough to get a five is not the same as understanding the subject. You might be doing yourself harm by missing out on the experience. Also, as a sophomore, you have all the time in the world - no need to rush straight to Physics C, especially since you’re still getting your footing in calculus. (Although, don’t be intimidated by people who say it’s hard. If you can understand how to solve problems, it’s all cake.)</p>
<p>So, if you want to get 5’s on the exams, it should be cake. If you want to learn the material thoroughly enough to build upon it in future classes, you might want to take a class for it, if not in high school, then in college. (But then, if you are going to take it in college, what’s the point of taking the AP test?)</p>
