I'm not one who learns much by reading alone. McMillan Study Guides are a blessing for me. (I'm using the PDG GOLD.)
I've been using PDG Advisor for two years. Both times I've scored high 80s (88) on my test. THIS YEAR I MADE SMSGT!!! This product really works!!!!! I scored 30 points over my cutoff!!! Thank you!!!
Great app! I was just selected for SSgt, and I owe it all to this app. Highly recommended. (PDG Suite for Android)
