It will be an excellent tool for iPhone and iPad users. I love being able to test myself anywhere. (PDG Final Exams! App)

I used the audio -- long and short -- and also AFH 1 Advisor. I studied for 6 months, 2 hrs a day, then a week before for 12 hrs for 6 days. I made TSgt by 12 points. Thank you, McMillan.

Wow!!!! The PDG and SKT software works. I increased my score 20+. McMillan, your system is 2nd to none.
