Oh, good catch - I totally forgot that one. In my state, you have to have at least junior standing (summer after sophomore year counts) and have at least a 21 (55th percentile) on the ACT in order to do dual enrollment. There's another category ("Opportunity Admissions") for kids whose birth cohort hasn't graduated high school, but it requires an ACT composite of 30 (95th percentile), which is a heck of a difference.

Dual enrollment kids get 6 credit hours a semester free; opportunity admissions kids pay for every hour.
