I'm going to be taking the AP Music Theory exam in May [along with Computer Science AB and Biology]. I'm currently only taking a course for the Biology examination, as I'm confident my independant studies can serve me well in passing both other two examinations. I do know that I am much more well prepared for the Computer Science test than the Music Theory test. I do know the basics of music theory, and have some ear training. I have been playing guitar for over four years. Can anyone offer any course material or advice I can use to better prepare myself for these examinations? My main focus is, of course, to learn the material. Passing the tests [with fives] is my secondary. Thank you for your time, it is much appreciated.
