So I purchased the online study guide for E7 and was promoted ... yeah, it worked. (CDC Advisor)

Please believe me when I tell you that you don't need anything else as far as the PDG. I literally took 8 days of leave and studied nothing but PDG GOLD. I studied maybe 5 hours every day just going over what they summarized and I scored an 83 on my test. Happily, I must say, I sewed on SSgt last November. I'm not book smart at all so this was my last effort and it paid off. If you're like me (not smart) it's for you. Good luck to whoever is testing this next cycle.

I made SSgt my first time testing with the help of the PDG Central app last year. I only used this app to study the PDG and scored in the 70s on the PFE! (PDG Central app for Android)
