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)

Results are out and boom - MSgt at 13 yrs in. I took 3-1/2 weeks of leave before my test and strictly studied PDG Advisor online. Made sure every section above the MKTS line was mastered at 85% or higher. Using this method, I achieved my highest PFE score ever. For the next few years, making rank will be difficult - so take the time and prepare yourself.

I made E-5 the first time I used your software. Now, I'm going for E-6 -- Let's do it! You're awesome!! I'm telling everybody! (Master Your CDC)
