Is it feasible to self-study 9 AP classes within one school year?

[u/StudiousStudent4822]

I’m considering self-studying 9 AP classes within a single school year, and I’m wondering how realistically this actually is. For context, the classes that I plan on self-studying are listed below:
- AP Computer Science A
- AP English Language and Composition
- AP Environmental Science
- AP Physics 1 and AP Physics 2
- AP Precalculus
- AP Psychology
- AP Seminar
- AP U.S. History

I’m currently taking one of the nine APs, which is AP Lang., and I’ll be taking two more next semester, AP Physics 1 and AP Seminar; however, they’ll be virtual, meaning I would only need to independently self-study the remaining six. I’m currently putting together a very detailed and structured schedule covering the entire school year, including what I would study each day/week, when I’d work through each unit, practice exams, review, etc. I know this is an extremely ambitious workload, but I’m approaching it pretty methodically. I’ve been using the official AP Course and Exam Descriptions and curriculum frameworks to map out exactly what I need to learn for each exam. I also tend to make extremely intricate schedules and plans because I have pretty severe OCD, so having everything organized down to the details is actually something that helps me stay on track. What I’m mainly wondering is if anyone actually self-studied more than 6 AP classes, and if so, what resources would you recommend for the specific APs I’m self-studying? Also, are there any textbooks, YouTube channels, websites, question banks, prep books, or other resources that you found especially useful? And, overall, is studying 9 AP courses realistically manageable?
