This was the only study material I used, and I just made SSgt first time with 20 points to spare! Well worth the money, if you use it properly. (PDG Suite NCO)

I studied for promotion about a year in advance using 2015 PDG Advisor, then switched to 2017 AFH 1 Advisor when it became available. I found the manner in which the program broke down the material and presented it to me was very helpful. Along with the final exam function and a paper copy of the AFH 1 (provided to me by McMillian), I was able to score a 97.97 on my PFE and promote to TSgt on my first try! I would highly suggest AFH 1 Advisor and the paper copy to anyone prepping for WAPS.

PDG Advisor is the best study guide around! I was selected for 16E7 and it was my first time testing without a promotion statement. Playing the study games made it feel like I was not even studying.
