3.0 GPA? Far too low a bar, considering how pathetically easy high school curriculum is today. Most high schools require no more than two years of science and two years of math to graduate (9-12).
FWIW, DUmmies, I did FOUR years of math (up to Calc), and SIX years of science (Gen Sci, Bio, 2 years each of Chemistry and Physics.) I still had to work my ass off in college, and later in Nuke School, back in college again, and even use a lot of it today. All you do when you set a GPA bar is create grade inflation to the point where showing up is a guaranteed B average.
The Japanese have it right--middle school, test out, separate the men from the boys, so to speak. You pass your exams, you go to high school which there is university prep. You don't, you go to vo-tech schools and get your ass a useful skill in preparation for the real world. Not everyone gets to go to college, and frankly, not everyone is cut out for it. But the unions and the cash cows that are public universities still try to pull the bullshit that a $150K education in Womyn's Studies is somehow marketable and will make you into something in life.
Oh, and another thing--I could go BACK to where I started college (a very highly regarded engineering school) for about HALF of what it would cost for me to get a basket-weaving degree from UNH right down the road. How sad is that?
