I use only this to prepare for my {sku} exam. I studied the questions 5 hours a day for almost a week. I passed my exam yesterday. No new questions there. All the questions in the dumps are valid and the answers are correct. I recommend the test engine because you can practice the questions in the real exam environment.

I highly recommend this site. I have purchased many perfect dumps for my certificate exams. This time their dumps helps me out, too. I ended up passing my {sku} exam after 1 month of using this book. 3-5 hours per night weekdays, 10-12 weekends. Can't say if this will be your experience, there were many topics that I had a good handle on before the test, but this book was a good reminder.
