I am finding this book to be informative. Very informative. I am a home school mom with a degree in Sociology. I've never taken Biology, but am learning right along with my son who is a Freshman in High School. It is challenging for him - but it must be. His plans for veterinary medicine require him to be challenged. I warn you (and the preface warns you) the materials are NOT easy! But, if your child fares well with this text, he'll fare well in College Algebra. Easy reading. Oh - you'll definitely need a microscope!
