Sorry it took so long to get back to you. YN A school is no longer self paced. I went almost 10 years ago when it was self paced. Even so, I still made friends... wasn't like I was in my own little world. I was on the waiting list back then about 6 months. Right now the wait according to EPMs A school list is about 18 months. TRACEN Petaluma does a wellness program that is mandatory for all the students. Your class advisor will let you know what to expect for workouts durring the workday.
Good luck at A school.
