@JD7777: What does your son want to study ? Any career goals ?
Is your son opposed to studying on the East Coast ?
With respect to another poster’s suggestion of Hendrix in Arkansas, I would encourage you to thoroughly research the current environment there before applying.
Flagler College in St. Augustine, Florida is very reasonably priced & a beautiful school in a spectacular location. Negative is the first year attrition rate. Interesting school. Should be an exciting change of environment for your son.
I suspect that the first year attrition rate of about 28% may be due in significant part to the imbalance of female students (65%) to male students (35%).
My concern for your son, however, is that he is well qualified for a most selective school based on his numbers and I encourage motivated students to challenge themselves. Nevertheless, for a very low cost option with very attractive & active students, Flagler College is worth a look.
