Excellent App! This app is amazing if you have time to kill on trips. Or sitting at work or anything else where you can't take your books! The app single-handedly made Staff for me on the first try. I answered 100 questions twice a day. Once in the morning and once before bed. Only picked up my book to review wrong answers. It might be expensive, relative to other apps, but it got me an extra boost in pay worth itself in the first month! Worth it. (PDG Final Exams NCO)

I've used PDG GOLD and PDG Advisor when I tested for both SSgt and TSgt, made them both my first time. Love the format and ease of access across multiple platforms. You've made a life-long customer out of me. Recommend all of your products to anyone who will listen. You're two for two in my book, batting 1,000.

I love your program. I made SSgt, TSgt, and MSgt using it. It is a great tool! (PDG GOLD)
