I am partly through the book. Some of the prose describing all of the code is tedious but there is much to learn. The examples at the ends of the chapters ae quite challenging and here is my complaint. The book is not advertised correctly. it is imposible to get the ansers to the examples (on CD) unless you are a recognized instructor with a certifcate. I know because I called Pearson Education support. This is quite a lot of money to pay to NOT obtain the answers, but that would be ok if if were plainly advertised before I made the purchase.
