I used PDG Advisor to study for Staff 13E5 and made it my first time, even with the percentage being 32.9%. If you stick with your study plan, you should make it no problem.

Not going to lie, I was skeptical about this but others swore by it. Prior to this I used the Promote app and did 30 points under the cut off scores. This year I tried AFH 1 Gold and I scored 16 points above the cut off which has been higher than the past three years for me. So despite walking out of the test feeling/thinking I bombed it and then I get shocked to find out I made it -- yeah I am a believer.

Master Your CDC is a great program! I passed with really high scores when I tested.
