Self Study AP Music Theory?

<p>Hi.
I'm not able to take AP Music Theory at my school this year because of my schedule, so I thought I'd do self study for it. I already have a good music background, and have played saxophone for 5 years.</p>

<p>So, .. What materials/textbooks/resources etc. should I use to self-study for the AP test in May?</p>

<p>Thanks.</p>
