Made TSgt and SSgt the first time both times. I swear by this app. Worth the money for me. Study wherever and read the PDG without all the queep. (PDG Suite for Android)

Well, after five tries, I decided to try PDG Advisor and I made it. Scored a 74 on PDG and 73 on SKT.

Well, this was money well spent. Your PDG & CDC programs helped me blow the E6 test out of the water.
