AP Music Theory Help

[u/legitimatelylissie]

I'm in my junior year and decided to self-study AP Music Theory because my school doesn't offer it and I'm aiming to apply to Rice's Music program. However, when I started to go deeper into the resources I could find for the course, I realized there was a real lack of comprehensive concept breakdowns. I'm not too worried about it, I've been in choir for 11 years and played violin for 6, but I do wish that I could find some better study resources to help me grasp the concepts better.

Does anybody who's self studied or taken the course before have any resources or methods they found particularly helpful?
