Note: I decided to stick with Exploring Creation with Human Anatomy and Physiology this year. It's very, very advanced, but I have decided to really shorten the lessons and this seems to make in manageable enough. It's going to take us a really long time to get through each chapter, so it will, naturally, take us even longer to work through the entire book. (I am guessing it might even take two school years!) But all in all, I don't think I will find a program that I like better, so we're sticking with it.
