I made TSgt using the McMillan study guides, and now I am working on making MSgt! Thanks for the outstanding study tools! (PDG Gold and Master Your CDC)

Perfect! This is the sole study guide I used this past year for studying. I started about 2 months prior to testing. I am not the best at studying and I get distracted easily. The app is very well organized and easy to use. Well worth the $50. I just made E-5 my first time testing thanks to this app. (PDG Central for Android).

I just wanted to say, "Thank you." Without you guys and your outstanding products, I would not have made MSgt. You not only got me ready for the test, but you helped me comprehend what it means to be a MSgt in the United States Air Force. (PDG Advisor)
