A normal homeschool family did just that! Cool story! http://www.today.com/news/meet-family-who-sent-six-kids-college-age-12-1C9316706
GREAT story!! I saw that, too, and I love how they made the point of the article that these kids are normal... they're not geniuses and they're not being pushed by tiger moms. They just enjoy learning, and they're allowed to learn what they want, as deeply as they want... just the way it should be!
