I read a lot of nice reviews and talked with people who use/used McMillan's programs and have nothing but praise for them. After testing this year, I expect I will be your biggest supporter, for your service and the program. (PDG GOLD for SNCOs)
I used the Master the PDG flashcards and they came in handy because I was able to take them everywhere with me. I scored 10% higher than everyone else in my career field.
I started using PDG Advisor when I found out that I would be testing for Staff. I made it my first time by 47 points!!
