If someone had given me these ideas when I was a kid, I would have done it this way.
I did my 4 years in high school and graduated with a lot of extra credits and had average to good grades. Some took the minimun credits and got all straight A. In college I graduated a quarter early with lots of extra credits. At least I did it my way.......but wish someone had given me this idea.
Just think of what you could have accomplished if you had the same degree 3 or 4 years earlier rather than 1 quarter earlier.
One of the reasons why a lot of people don't go to grad school (myself included) is that they get burned out on so many years of schooling. I don't see much of a way to avoid the 4 years of trudging through college, the best you can do is shave a quarter here or there. But kids today can completely skip the wasted time of high school and avoid the burnout phase.
