University efforts are best spent taking those who are ready and capable and stuffing their heads full of new ideas. There are people who are not ready or capable, but trying to find ways to slip them in and hoping they reinvent themselves in time to take advantage of the opportunity (if that's even possible) would be neglecting those who are ready - many of them would end up in remedial classes or just taking the easiest things possible to survive. Maybe they should wait a year and wander Europe, or otherwise take some time to get their life together first.
I was one of the C-B students who did all the gifted classes in high school but never had the grades. When I went to University, the first two years I loved the freedom and the content of the classes but was as lazy as I had been in high school on the grades. It was only later that I started taking things seriously. The first two years might as well have been wasted, plus I chose a university well below par for my abilities (wasn't even nearly the best one I got into). I think I turned out pretty well looking back 18 years later, but statistically, I was probably bad betting odds. Universities should focus on people who are actually ready to learn, rather than figuring out ways to churn out more people who are likely to drop out. Slashdot, in turn, should stop pandering to people who never learned to focus who drop out of university and console themselves by extolling the virtues of being an autodidact, of not knowing how to dress or clean themselves and paint themselves as "natural" or "different" or "fighting the system", and similar.
