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)

Thank you very much for continuing to exceed customer expectations. And thank you again for your commitment to the Air Force and helping NCOs prepare themselves for advancement.

Thank you for your product. This is the first year I have used it to study for promotion. I scored a 77.77 on the PFE, which was 96.08% higher than everyone in my career field. Best money I have ever spent. I would recommend your product to everyone testing! And thanks to you, I am a TSgt Select! I will be purchasing again when I study for MSgt. Your products are awesome!
