So far I have completed the Windows 2000 Professional and Server exams and have always found the Readiness Reviews a crucial element in studying. This book is no exception.
The book tests your understanding of the exam material with questions of the type and format you will see in the exam. The best thing about the book is each question is broken down with an explanation of why the answer is right and why the others are wrong.
You will also find that the book teaches you to pay attention to what the question is asking or looking for. This skill is important as the exam questions on the 70 -216 are long and take time to understand.
As mentioned in other reviews on windows 2000 exams do not rely on one book alone.
