PDG GOLD and PDG Advisor helped me reach my goal of being on the 13E7 list. Now, I'm ready to study for SMSgt as soon as the new PDG comes out.
McM has helped me prepare for E-5, E-6, E-7, E-8 and now for the last one, E-9! (PDG GOLD for SNCOs)
I was going to deploy and test for SSgt out of cycle; however, it fell through and I had a week and a half to study for SSgt. I bought PDG GOLD and studied that alone for a week and a half and made SSgt my first time, ranking 17 out of 300-something selectees.
