I always used McMillan when I was in the Air Force. I retired as Chief, but now my son is on my heels, so I want him to have the best study guides!

I would like to post an excellent review. I used PDG Advisor while deployed to Afghanistan. This product had me studying over 60 hours before my first ever SSgt test. I was the number one selected in my AFSC and set the bar extremely high by destroying the cutoff score by 42 points. Your products work, and I will be using them again in the future. My score and line number say it all 10/10.

I have sworn by your products for over 15 years. I received my line number for MSgt this year. Again, thank you for supporting all of us in succeeding in our careers.
