I love, love, love this product (PDG GOLD). Used it to study for a couple hours a day for one month before testing for MSgt. Increased my score from last year (sans studying) by 36 points. Guess what? I made it this year. Missed the cutoff by 19 points in 2010 and made it with a 40-point cushion in '11. Your software works! I'm a fan for life. Can't wait to use it when I test for SMSgt!
