I saw this first-hand when I went back to school at a local community college just a few years ago. The washout rate that first semester among the eighteen to twenty four year-old group was close to 50%. Of course, not all those who wash out are incapable of doing the work, often its the case of just plain choosing not to. Many high schools cannot give a student an F and instead can only give a D as the lowest grade. When they get to community college, they figure its still a free ride. They are shocked and outraged when this turns out not to be true.
