Our experience was different, but we were really focused on adding socialization from courses with others to academic needs being dealt with in part from homeschooling. So, we partially homeschooled ShawSon. We did not use college courses but our public HS is highly ranked in a state that is ranked as having great school systems.
ShawSon was and is ridiculously gifted and severely dyslexic. The HS really was not teaching him how to write (or, earlier in his education, read, but he’d mastered that). Also, some courses like HS math were trivial for him (he covered junior honors math in 3 hours a week in one semester and got a perfect score on the final). But, ShawWife did not want him working solely on his own or with only a tutor.
So, he took lab science, art and social studies courses at the high school. Again, the main reasons were socialization for a math/computer/strategy/board games nerd – he wasn’t running into a lot of females in that crowd – and in the latter two, pretty good instruction. We wanted him to socialize with other kids and have some exposure to females. It worked to some extent. He competed in Moot Court and made friends there and created some clubs (one focused on games of strategy IIRC). With respect to females, much more modest success but ok.
Interestingly, he had a lot of recommendations but the Deputy Superintendent of Schools, who had suggested partial homeschooling after seeing his psychological testing and meeting with me, offered to write one of his recommendations.
