Good for him, I mean that...but you know what prominent recent politician was also a governor at Boy's State though, don't you?
...He applied to 4 colleges, was accepted at all with scholarship offers...
Seeing your state flag, I trust perhaps Emory, Ga. Tech, maybe Ga. State...but, please don't tell me that school in Athens where "How 'bout them Dawgs!" rings in your ears and you're abused by inhospitable, barking and drunken rednecks attired in read and black and hollering "Dawg Meat!" if you dare enter 'tween the hedges in an opponents colors. I got beer poured on me, and I was spat upon and generally had my life threatened there in the 1970s, whew, and I thought Philadelphia Veterans Stadium was bad--it was like a 4-star hotel compared to Sanford Stadium!
You said that homeschool students weren't socially adept and I gave my son's Boy's State experience as an example of his social skills. He has always had friends and he has always been a leader.
We are from Ga but now live in NC. Our son didn't apply to any GA schools. He is at school in VA, very old school, very pricey, very preppy. Many of his classmates came from exclusive prep school backgrounds. (Prep school seems to be a biggie with you.) I'm just trying to make the point to you that our son is able to compete and even excel when you've judged him ill prepared to do so.
PS. Maybe poor socialization in the public school environment created the problems with that prominent recent politician you mentioned. ;)
