I was homeschooled from 7th grade all the way to college. Apart from the fact that it tooke me a little while to get used to exams again once I was in college, I think my education was right on par if not better than what I would have gotten in public school.
I am sorry I cannot elaborate more at this moment as I am in UConn taking finals this week. However, on Sunday I will be home, so I will take some more time and tell you more about my experience.
For now, check with your school system to see what the requirements are for your state. I live in CT and here they are very lax about it and don't even require me to check in with anyone. Your state, however, may have standardized tests, etc that have to be completed every year.

More later,
