This works!!! I made SSgt by 24 points! I would also advise reading as well. DO NOT JUST DO MULTIPLE-CHOICE! Don't be lazy. Work for what you deserve to help others.
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 DID IT!! I got selected for TSgt this year. I downloaded the audio, listened to it all the time and it made the difference. AWESOME.
