More than one university tried to recruit me before I'd even started high school, based on the results of an SAT test I was asked to take in 6th grade. I didn't go, but mostly because no one offered a full-ride, and my family was poor and couldn't afford to pay tuition and put me up in another state.
Sophomore year, I scored highly on the ACT. Before dropping out, I was given conditional acceptance, as long as I completed a GED.
