I love your products! They seem to get better each year. I used a combination of your products while studying for SSgt-MSgt and made it every time! (Master Your CDC and PDG GOLD)

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 really like this product. This is a great app because it is easy to take everywhere and you don't have to carry a stack of note cards or a whole computer with you just to study. (PDG Final Exams! App)
