Nope. We learn the material over (having been out of school for at least two decades) from the home school material, and then teach it.

If you don’t have patience, but also can’t afford private education of some sort and have to resort to broken public institutions, there's not much hope (imho). Patience is cheap (comparatively speaking).

I've learned how to weld, sail, wrench on diesel engines and my Teslas, perform wilderness EMT procedures, woodwork, and build houses/perform large scale home improvement on my own. K-12 is a cake walk. Don't doubt your vibe, you're a fellow human and you can do it too.
