Thanks everyone for the wonderful advice and encouragement. Yes, the K12 curriculum would be free for us through a state charter school. According to them and other parents I have asked the curriculum is very flexible and a child can work at their pace. They also do a placement assessment, and they were open to look at our Explore test results if anything shows up there. So those are the pros of this curriculum.

The one aspect of homeschooling I am nervous about is making sure I provide a well rounded education for DD. Since I didn't get my education in United States, I'm not sure if I would miss topics that kids here should know before college. That is why an eclectic approach would worry me. Our friend's child does about 3-4 hrs of school work every day and if this is the case with DD, she would have plenty of time pursuing her interests. Maybe as I read and learn more, I would have a better grasp on the larger picture of homeschooling and a comprehensive curriculum.
