Here in MI only the SATs are required. Other states are different. We plan to send out girls to 2 years of a local community college before a big school. This way we can guide them as they get "socialized" (LOL). At the rate they are learning, this should be next year. (hehehe, they are 4 & 7) No really, I think the local college starts at 16 years old with an SAT.
What's not to like about homeschooling ;) ? And sheesh, between Pony Club, 6 afternoons a week working at the barn, eventing, hunting, music lessons and recitals, blah blah blah, I have to keep a calendar just to keep up with her social calendar just so I can figure out her transportation needs.
