I was selected for promotion and will sew on SMSgt on 1 May. Test score went up thanks to PDG GOLD for SNCOs and your pocket-sized guide - PDG ReviewNotes.
PDG Advisor is a great product. I made SMSgt in 15 years because of your product and suggest it to all of my Airmen.
Used PDG GOLD and Master Your CDC - passed both tests on my first attempt. Worth it!
