Thanks for excellent info! It's good to know there's someone in same situation a mine. The anxiety has just eased a bit. More questions:

The online programs, do the good ones provide an official transcript, for presentation to local high schools if parent wants to re-enter school system? Can public and online course be combined? For example, would child be in public school english class and then at home, take online Shakespeare course at same time? I don't imagine public school allowing child to skip their english class, but then again, I don't know.

What's the outcome for a gifted child who (for financial/social/other reasons) remains in mediocre public school system, but participates in outside weekend gifted programs, private music, selected activities outside school. But remains in "boring" 6-hour a day school system where the goal and culture is sports and not about excelling in personal strengths and going to a good 4-year college. Emotionally and mentally, is child still feeling good at the end? Or disillusioned and frustrated?

Will gifted child lose interest in "school"? Will study habits ever be learned to prepare for college?

Are the offered AP courses enough to challenge the child? Can a child who doesn't need to study in middle school to score high even do well on AP courses?
