Is taking all 4 worth it?
Not generally. There is significant content duplication so that you will not get exemption from more than two semesters of college physics (and may get none).
@ucbalumnus At our school, the exams are offered, but classes are not. I’ve taken Physics 1 last year, and I’m planning on taking the Physics C exams this year. Is it ok to take the physics 2 exam for the heck of it?
Check whether they will actually be useful for you intended college major at your colleges of interest.
Alright, thank you!
