Query: A real Lack of Information

I bought this book for class at my technical college. Although mine was a second edition it read like an unrevised draft, edited only for grammatical errors. The inside cover even lists objectives for the Server 2003 exam, not the XP pro. exam. I took the 70-270 exam yesterday and earned a 610. About 30% of the questions pertained to information that this book either never mentions or does not cover adequately. Questions asked at the end of the chapters are frequently worded poorly or can't be answered using the book. Don't waste any more time looking at this book or this review, go back and choose something that has positive reviews. I went to the bookstore and browsed their XP pro. books after the exam. The difference was night and day!
