Client Testimonials

"Wow, you guys are awesome"

Kevin Hunt

"I passed my exam with 40/40. The training was helpful; I have been in IT a long time but those specific test strategies made the score what it was. My execution was as follows: I went through all 40 questions and answered what I thought was best. Then, I went back to the beginning and read every answer and made myself figure out which answers could be easily eliminated and which were more likely answers. I also noticed patterns among questions so that I could flip back and see how some questions helped with other questions' answers. I actually changed six of my answers in the second run-thru of the test; that is unusual because usually the best strategy is to go with your first answer. It was using the strategy you taught us of reading every answer and making myself figure out what the other options were (e.g. the answer was "major incident management" but the other options were the definitions of "emergency change," "release management," and "warranty") that gave me that perfect score."
