I always encourage our Airmen to use your study guides and computer programs to enhance their study habits. You have a great, fun and easy-to-use product. Keep up the great work! (PDG GOLD)

Thank you for making PDG GOLD for Macs!!!!!!!! I used PDG GOLD, Flashcards, The PDG Choice Manual, and the Audio CDs for about 6 months before my test. I increased my PFE score by 24.82% and blew the test out of the water! That TSgt examination is tough, but I felt more than prepared after using the McMillan study guides!!

I really enjoy your products! They have been extremely helpful to me in promotion testing. I use almost all of them. In the past, I used the computer program (PDG GOLD) and found it to be wonderful ... Thank you for your continued production of great products, and I look forward to using them for many more years.
