Very good! I read up to and including Pivot Tables. It feels good to finally know what the heck are pivot tables! There are plenty of pictures to guide you and the instructions are well written, except for one thing, and this is why I gave it 4 stars instead of 5. In the beginning of the book, it is explained that in order to guide you, a ribbon name will be given, followed by the ribbon's category name, followed by the button you should click. Well, the ribbon name was often ignored, so I was hunting down the button I was supposed to click.
Highly recommended.
