Yeah, good point, especially at the higher levels. Our public high school offered differential equations as the level after calc only because they randomly had a really exceptionally capable math teacher who was a teacher as a passion project after he'd made his money elsewhere, but most schools don't have access to that sort of capability. Remote learning could offer that sort of headroom in every subject. I guess local colleges sometimes offer that ability. Maybe some charters do, I'm definitely not an expert.
