<p>I agree with most of the posters that taking the AP test won’t matter for music schools, although it could help prepare you for some the of theory tests they will give as part of the application process. Most colleges don’t give credit for many AP classes (because AP classes are like the Platte River: a mile wide and an inch deep).
However, my son took the AP Music test last year. He recommends checking out the college board site…they have some previous tests. If you’ve had a lot of theory, it really shouldn’t be too difficult. Good luck!</p>
