CDC Advisor really made a difference for me. Last year, I scored a 57 on my SKT. This year, I scored a 75 and made MSgt!

First time testing. Bought PDG GOLD, studied approx 1 hr each day for 3 months prior to my test. Clocked approx 2.5 days in PDG GOLD. Scored an 87! Thank you, PDG GOLD!

I've been using your guides and CD-ROMs for a few years now ... my scores have improved by 10-12 points since using your study guides. Maybe this next time testing for Tech will be GOLD! Thanks for your great products! (PDG GOLD)
