PDG Advisor clearly tells you what is higher in the MKTS Survey and therefore what would be most important to study.

I have used your software many times with great success. Made staff sergeant my first time, and scored a 90% on my 7-level CDC's. (PDG GOLD and Master Your CDC)

Your software was very helpful and I found it covered about 75%-80% of the book material. I increased my scores by nearly 25 points and I sincerely believe it was due to reading the book as I verified answers to your questions. I anticipate using your software again in the future. Thanks. (PDG GOLD)
