[quote=Anonymous]OP here. The cost to which I am referring is the stress and countless hours of work required by AP classes. Graduating college early is commendable and would save on costs, but how many people really do that? If AP classes are really preparing the students for college, why are the 4 year graduation rates so low,between 19-36%?

And colleges seem to be moving to the 6 year graduation metric.
"The overall national six-year completion rate for the fall 2009 cohort was 52.9 percent...after six years, fully one-third of the starting cohort had left higher education without earning a degree or certificate."

By and large, the college students not graduating in four years were not AP students in high school.
