I was very sad to see that Dr. Wile's name is no longer on the text, but his writing is still intact. This text underwent a much needed graphic overhaul and we're finding the results to be fabulous! The updated illustrations and additional microscopic photographs are super helpful.
You need to be very careful about ordering the correct coloring book. It's not the new edition of the old Kapit book, but the new edition of the KAPLAN book. Since the new edition of the Apologia Human Body book was released so close to the beginning of the school year, many of my students' families were confused and we have multiple edition texts and coloring books in the class.
Overall, the text is excellent quality and I'm thrilled that Dr. Wile's writing and style is still intact.
I used the first edition with older son and I can't emphasis enough how tremendous this revised and updated edition is in comparison! What a HUGE improvement!! My younger son loves it and it's so much easier to follow with the color, sidebar notes, etc. Highly recommend!
