Another thing to keep in mind is that everything is negotiable
and it never hurts to ask, I have several friends both in the US and in
overseas who attended colleges that didn't "accept" homeschoolers.
Visit the college, talk to the people in charge and bring examples of
your child's work. Think of it as a store and you are the customer (and
the customer is always right)
Don't give up if they say the don't "accept" homeschoolers
hope this helps
