What needs to be shouted from the rooftops is that even if they HAVE taken the classes, they're still largely unprepared; try finding a public university today that DOESN'T have remedial math and English classes for those 'college-bound' youths who miraculously got in. Thank the dumbed-down, feel-good, grade-inflation high schools for that.
And the concept that most or even half of high schoolers SHOULD go to college at all is ridiculous. It's like saying most graduates should go into the waitressing field, or learn to weld. College today is oftentimes an extension of adolescence and a deferral of becoming self-sufficient, NOT a quest for knowledge and wisdom.
