content: I have read the first book out of the four (Windows 2000 Professional (70-210). Studied it inside and out. Took the sample test in the CD-ROM and got 98% on it. I thought I was ready for the exam so I went and took the 70-210 exam. Well, this book did not even come close to what the exam was like. The questions were much, much harder and longer scenerio type. I did not pass the exam. If you are looking to just learn Windows 2000 Professional really well, then these books are good. If you are looking to take the MCSA or MCSE exams then don't count on these books to help you pass.
