Perfect. This is the sole study guide I used this past year for studying. 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 the app. (PDG Central app for Android)

I just wanted to say thank you for creating excellent testing software and providing amazing customer support. I tested for SSgt and made it with points to spare my first time. I'll be back when I test for TSgt. (PDG GOLD and Master Your CDC)

I bought PDG GOLD for my laptop and the Master the PDG single-answer book. I made E-5 on my first go-around. The test questions and answers just seemed to pop out to me. Many people use different methods and techniques to study. The PDG study guides are my technique and they worked for me. Thank you.
