I bought PDG Advisor and blew it away! Thanks to McMillan! I don't know where I would be without McMillan's study guides.

I love the free PDG Final Exams online. On my first exam, I got 51%; on my second, 58%; then I got 98%. They're great! (Test Me Now!)

Used both PDG GOLD and PDG Advisor plus listened to the PDG audiobook for 6 months. I made SSgt my first time; 26 points above the cutoff!
