By far the best investment in ensuring you pass your CDCs with solid scores. I will always turn to McMillan Study Guides throughout my Air Force career. Thank You, McMillan! (Master Your CDC)

Master Your CDC for my 5- and 7-level are awesome! I love it!

I believe your testing material is what helped me to pass my test for Staff Sergeant the first time. I have a goal to make Tech the first time also, and the PDG GOLD combined with Master Your CDC are part of my studies to achieve that goal.
