This is not a well-grounded suggestion, but FWIW. Child stars (e.g. film) -- or their parents, although the child's income may well be paying for this -- hire tutors. They cram in concentrated, often one-on-one tutor time and independent study on top of often full schedules. In part, the concentration and quality may reduce the total number of hours required. I don't know this person's income, but would something like this be an option? Combined with "graduating" early? In this case, he might be taking the initiative himself, rather than through a parent. But the mechanics seem workable, even if this is not within some established paradigm and set of expectations. In the business world, rather than e.g. the film world, this person might be considered a "star child". Why not afford him the same opportunity that a film star would have? I don't know the socio-economic position of this "[private school]", but this sounds as if it's in the U.S., and "private school" and some other content lead me to assume a few things: Both parents are in careers and/or otherwise too engaged to consider home schooling. There may be enough money in the family to help with private tutoring in addition to or aside from the kid's own income. (Much private schooling in the U.S. is not cheap.) From the language used in our protagonist's letter to his principal, it appears to me that he could benefit from some additional education. At least in written English, there is room for improvement. So... get the degree, and some additional education. But do it your way, with a concentrated curriculum and instruction that provides the most useful concentration possible while eliminating as much of the bullshit and crap as possible. Just a suggestion for consideration.
