I just finished the exam and came to office. I used this dump. It was useful. But there were total 48 questions. Exam was scheduled as two parts. One with 23 Questions and Other with 25 Questions. You have to finalize first exam to start the next. The critical information is that there were around 15 questions I got out of this dump. So better to refer some other materials as well. Studying only this will not get you through.
