I used this software to complete my CDCs and it was excellent! I completed six years of Active Duty and now I joined the USAF Reserve. I'm switching jobs and hope that the Master Your CDC programs works great again!

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