i'm an engineer and have not much time to prepare for the exam. Before two months, one of my friends intriduced this dump to me. From then on, I only planned one hour to study this dump and do the questions. Sometime i was so busy and had no time to do it. So before i begun my exam, I think I would fail the exam. But when i begun the exam, I found many same questions with the dump, so i felt more and more confident and at last i passed the exam luckly. Thanks for this dump and special to my friend.
