I was selected for promotion to SSgt. It was my first time testing and I also had BTZ under my belt. So I figured it was a long shot with the 15-year low percentages. Ranked 5th in my AFSC, probably right behind the 7th year SrA. (PDG Advisor)

By far the best investment in ensuring you pass your CDCs with solid scores. I will always turn to McMillan Study Guides throughout my Air Force career. Thank You, McMillan! (Master Your CDC)

Just wanted to say that PDG Advisor and CDC Advisor are awesome study tools. I was able to blow my test out of the water and promote my first try.
