<p>I self studied for all my APs (my dad helped a lot on the science ones) and then talked to the local high school about taking the exams there. You can usually find recommendations for good textbooks if you search ‘AP (subject) textbooks’.
The cool thing about homeschooling is that you can start early, finish early, and leave yourself a couple months to go through a AP study book (I liked Princeton Review’s the best). And make sure to take advantage of all the past free response questions on the collegeboard site to see how you’re doing. 
Good luck!</p>
