It helped me make SSgt, TSgt, MSgt and I know it will for Senior! (PDG GOLD for SNCOs)

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).

These programs definitely work, as long as you put the time and effort into your study regimen. I made TSgt first time by almost 40 points! (PDG Advisor and CDC Advisor)
