I used the iOS App (to make MSgt) on my iPhone and it was awesome. Very convenient.

I just received my results for SSgt and I made it the first time. I purchased the PDG Choice manual and I'm certain it is responsible for helping me score 64.75% higher than my career field! Hands down, your products work. THANK YOU, McMGUIDES!

PDG GOLD is the best and easiest way to study. The games make it fun to study.
