How dual credit changes this math
Students in most states can earn college credit during high school through dual enrollment, AP, and CLEP, often at a small fraction of university prices. Done right, that means entering college with a semester or more already complete. Done wrong, it means credits that transfer but satisfy nothing: roughly 1 in 7 dual-enrollment courses is denied at transfer, usually for degree fit.
