I used PDG Advisor this past year to study. I raised my score by 13 points and made an 80 on my PFE. I still missed TSgt by a wide margin but do not feel I could have been more prepared. I scored higher than 95% of those eligible, so next year it's in the bag using PDG Advisor.
The new games are GREAT!! Really fun way to take a break in between studying. I REALLY like the PDG Danger Zone. It is a blast to see how far you can get the book to go.
It helped me make SSgt, TSgt, MSgt and I know it will for Senior! (PDG GOLD for SNCOs)
