I received a 73 on my AUD becker mock exam, and a 75 on my actual AUD exam. However, I feel like this is a more unusual bump and the average bump for this section is like average 7 points. Some of my AUD sims were heavily tied into FAR, and I would have failed if I never looked at FAR (maybe refresh on basic journal entries, nothing too complicated though).
AUD - 75 BEC - 86 FAR - 84 REG - 78
No one ever fails the CPA, people only quit the CPA exam.
