I used your 5- and 7-level study CDC software and made E-7 this cycle...all total that's E-5, E-6, and E-7 thanks to you guys!

Tons of props for PDG GOLD! Used it to study for SSgt back in '08-'09 and made SSgt first time! Pinned on two days before my four-year mark!

Your software makes studying so much more enjoyable. Kudos to whoever designed this software!
