You're right. In a way, I was able to get school out of the way so I could learn.
There are still requirements to meet. We had standardized testing every year, and coursework to complete. My point is that I could get the formal stuff out of the way at my own pace, and actually do interesting things like learn about aerodynamics first-hand. At a public school, this would have been more difficult to do.
Gives the legal requirements in the UK. We don't have requirements to sit exams or do specific pieces of work (coursework) as long as "full-time education" is provided.
