Those of the Harding siblings who have already graduated from college have gone on to become a doctor, an architect, a spacecraft designer and a master's student. Another two – 12- and 14-years-old – are still finishing up their degrees.
But despite the Hardings' incredible achievements at such young ages, their parents – Mona Lisa and Kip – insist they are a family of 'average folks' who simply find and cultivate their children's passions early on.
Hannah was the first to take her college entrance exams – at the young age of 12. 'I didn't expect to pass,' the 24-yead-old told Today.com. 'So I started crying, because I was thinking, "Now what?"'
She passed the exam and, at just 17, became Auburn University Montgomery's youngest ever graduate, obtaining a BS in mathematics.
Hannah went on to get master's degrees in math and mechanical engineering, and she was designing spacecraft by the age of 22.
