<p>dstark, I think the 80% number is really high. I would guess more like 50% are happy or at least learn to adjust. If we look at all colleges, there are a lot of students who really don't belong and don't graduate. </p>
<p>Since I am just guessing, I looked at the Dept of Ed webpage and checked graduation rates and transfer rates. The top selective schools have a dedicated student population and graduation rates are high. I was shocked when I looked up some state universities and less selective private schools. Many had transfer rates of 30% and graduation rates of less than 50%.</p>
