The book is outlined very well, but it can get confusing trying to remember what color you used on a previous chapter and now need to use in the new chapter. They only give suggestions on the colors like use light or dark colors. Very rarely do they come out and say use this color for this thing. It would be better if they had already set up what colors you should have colored the different body parts. Some of the information could use some sort of reference system so you can easily identify related areas of study ex. go to page so and so for related areas. The art work is good for the pictures, but make sure your colored pencils are very sharp there are some very small areas you have to color. When using the book you will find yourself jumping around from chapter to chapter to cover the needed information for what your teacher assigns.It is still a very helpful study aid to have though and certainly better than nothing at all. Happy coloring.
