Used Master Your CDC to make Staff - it worked great! Now, I'm ready for my 7-level.

I just wanted to take the time out to send McM Study Guides, Inc. a thank you for all the customer service you've provided me and for releasing these study guides in the first place! I used these guides and made E-6 my third time and E-7 my first time this year! The only regret I have is not picking up on your study guides much sooner. I will definitely be purchasing these guides again when it is time to go up for E-8 and hopefully blow that portion of the test out the water like I did the previous two. Thanks again!

Thank you so much for all you do. I'm a single parent of two and PDG GOLD helped me make E-6 while in Korea, separated from my children. I'm determined to make E-7 this year and have faith that PDG GOLD will once again help me obtain my promotion goals!
