I used PDG Advisor for about 3 months and earned TSgt on my first attempt. In my opinion, it was worth the cost.

I made MSgt using PDG Advisor. I scored an 80 in 2014 and missed it by 0.5. In 2015, I scored an 85 and made it by 65 points in combination with board score. Thank you, McMillian Study Guides!

I went into testing at a disadvantage with just a "Promote" and an average board score. I decided not to let those slow me down and purchased PDG and CDC Advisor, and the PDG Audiobook. I scored 20 points higher than the average on both tests, and I made MSgt by 30 points. That's the second stripe I owe to McMillan.
