@ucbalumnus,
Maybe so. But mine took mostly major requirements for studio art and general education, as she once considered getting early college degree in fine art. Many, actually majority of a few kids I know focused on the long Calculus and Calculus based Physics sequence as it was their passion. Another one took Chemistry - Organic Chemistry sequence because organic chemistry is the most easy and fun thing for him.
And some stay in community college years and years, as mine could have done if she didn’t want to go to high school, and accumulate 100++ units in many general education and major areas.
I am coming from (gifted) homeschooling community, and my experience isn’t normal.
