I sincerely believe that if you are ready for a biology curriculum, and want one that is comprehensive, fun, and engaging, this is the curriculum to use. Further, if the whole thought of biology makes you squeamish and you’re thinking that this area of study is one that might have to be skipped, check into this curriculum. You’ll not be disappointed and, more importantly, I believe your child will have a great time learning biology.

My son has learned so much more because he had to pursue and find the answers, rather than reading a dry, boring textbook. I also liked the way the biology material starts with the study of life.
