The PDG GOLD has helped me get promoted to TSgt, MSgt, SMSgt, and just recently Chief.

I am a Major in the AF ... I will have you know that in my 18-year enlisted portion of my continuing 27-year career, I have used McMillan Study Guides many times in the past with obvious great success.

Made SSgt on my first try! Used PDG GOLD to study. Good resource. Highly recommend!
