I've used PDG GOLD, Master the PDG Flashcards, and Master Your CDC each test cycle and they're the reason I made MSgt first time.

I was just selected for MSgt, thanks to PDG Advisor.

I used Master Your PDG book (Single Q&As) for the first time in 2012 when testing for E-6. My score jumped twenty points and I was the 10th highest in my AFSC. This year was my first time testing for E-7 and once again, this book landed me another stripe! Great product! Thank you, McMillan!
