This is exactly what I have been looking for in an app. Very easy to use. (PDG Final Exams! App)

I used PDG GOLD to study for my second time testing for MSgt, and I made it by over 15 points. Last year, I missed it by 30 points. Thank you, McMillan.

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.
