There were only two times when I scored horribly on the PDG and SKT promotion tests and didn't make the next rank - that was when I only used AFPAM 36-2241 and not Master Your CDC and PDG GOLD.

Used PDG GOLD and Master Your CDC - passed both tests on my first attempt. Worth it!

I love McMillan products! I've used them throughout my career and always had success! (PDG GOLD)
