I have recently been getting acquainted with my biological father. One of the interesting tidbits he shared with me is that he graduated high school and went on to college at age 15. He wasn't successful at college that first go round though, and went back a few years later to complete his BA and get his masters.

I think it's more common these days, or maybe just we hear about it more. In any case, I always think it's nice to allow people to go forward at their own pace!
