None of the questions you see will be word for word on the exam, like what you see on MS exams. And most of the questions like the ones from Wiley, Shon Harris, and the Official book all have errors in them. Even some of the ones on cccure are wrong. I would suggest when using cccure to track which domains you do worst on. That will give you a good idea on what you need to restudy. Also, doing a high level refresher overview a day or two before the exam is a good idea. The exam quesions themselves aren't that hard, its more of an endurance thing because there are so many questions. It usually takes most people 3 1/2 - 4 hours to finish.
