I've used PDG GOLD and PDG Advisor when I tested for both SSgt and TSgt, made them both my first time. Love the format and ease of access across multiple platforms. You've made a life-long customer out of me. Recommend all of your products to anyone who will listen. You're two for two in my book, batting 1,000.

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!

Just found out I made MSgt my first time testing, thanks again to PDG Advisor and CDC Advisor!
