Using it to study for my high school a & p honors class, and I am crushing it with a 97%, so take that as evidence of this book's awesomeness!
Great visual diagrams, workbook is good too, only sad thing is that the pages are double sided and so thin that even mildliners bleed! and I can't cut them out to put in my bullet journal, so I've been having to draw diagrams free-handed in my journal, which...does not look good, trust me.
