I'm currently a senior in HS, and I've gotten a 5 on the Physics B AP exam and hope to get a 5 on the Physics C AP exam (mech and electro). I asked my teacher what I should do (I'm going to University of Texas at Austin; ME major) about the credits. Some posters here at this forum have told me that I should never use the credit because I'll be dealing with physics so much in college. Plus, I didn't get a proper education and understanding of post-mechanics physics in my Physics B course. On the other hand, my teacher advised me to go ahead and take the credits so I could skip those intro courses. She said the reason for this was that intro Physics classes were designed to weed out students and were ridiculously difficult. As a bonus, I'll be saving quite a few hundred dollars and quite a bit of time. I believe I'm as adequately prepared in algebraic mechanics as a high school student can be. I'm not so sure about Physics C's calculus-based physics though, however there's still quite a bit of time till the exam. So my question: Should I go ahead and skip the courses that Physics B/C would exempt me from? Or not take the credit and struggle through the weed-out classes? Thanks a lot in advance.
