I would suggest you run the net price calculator on each college website to see if YOU can afford to,send your child there. That is far more important than average cost!
In terms of graduation rate, we agreed to fund four years of undergraduate college studies. Anything beyond the four year mark was on our kids…unless it was because of some kind of emergency or health situation. So,for our kids…the graduation rate in four years for THEM was expected to be 100%.
