@NotherBen - no 'study hall' this year, though last year he had something that amounted to that in first period..so that helped a lot. not much to catch up on when he would return from a bought of exhaustion.
PE is pretty strict about doing the work, and parental sign off is very limited, but maybe they will suggest an exception.

Sorry I did not say before, home bound would mean a teacher for min. 2 hrs per week per subject. that would be minimum 6 hrs, still a lot less than the 20 hours he'd have to be up and about and in classes if he stuck with regular class.
