I used PDG GOLD and Master Your CDC when testing for 15E5. I missed it my first time in 2014 by 8 points because I didn't put in the time to study. I wasn't going to make that mistake twice. By using these programs I scored 24 points above the cutoff score and am now a SSgt! Definitely worth the money and the time.
Word of advice for anybody testing. What you put into the test is what you'll get out. PDG Advisor breaks down the information into easy to remember sections. I would highly recommend this product to others. I made E-5 first time testing by 23 points!
I just wanted to let you guys know that I won your product last year and finally made MSgt by 50 points! I beat my AFSC average by 14 points. Thanks McMillan!
