I've been a heldesk technician for less than a year, so I was nervous about taking the exam. I bought this book and the Exam Cram, and they did the trick--especially this book. The book is easy to follow, has all the basics, and gives you good test prep drill too. In retrospect I probably didn't need the Exam Cram. In fact, the other book that was pretty useful is the Windows XP Resource Kit, edition 2.
