I think this book tries to overwhelm someone trying to teach their child. I can't imagine a child being happy being taught so rigorously and will be isolated and overstressed with such intense hours of school. (A lot of public and private schools have the same problem) I don't trust the advice of teaching about all religions at such young ages. They need to be grounded in their own culture and religion first. I'd get a simpler construct of a classical education or you'll go nuts. Also, read John Taylor Gatto for guidance.
