The training kit is a nice method of studying for the MCSD exam. It covers basic to indermediate Visual Basic programming. However, it may not be enough to pass the exam.
In order to fully take advantage of this product, you will need to do the various examples in the book and understand what is happening. Some of the most important topics, like ADO, will require additional learning. The MSDN CD that ships with Visual Basic should help here.
For those who are not up to the level of this book, the CD-ROM ships with a copy of Learn Visual Basic Now, which should get you to the the level you need to be to complete this Training Kit.
My biggest problem with this book is not the material, but the stupid typos. For a company that prides itself on its spell-checking ability, typos like knoe (for know) are absolutely unacceptable. Fortunately, the material is much better than the spelling.
