Well, it depends on what the definition of "graduate" is. I would think all they have to do is pass the "condom on the cucumber" exit exam, and they're ready for the world.
Touche! When I taught college in the 80's, 80% of entering freshmen could not pass entrance exams and had to do a couple of years of remediation before they could read, write a paragraph, or compute well enough to begin college work. As we all know, there are a lot of HS grads who cannot make change.
