It took me 6 times to take AUD before I passed it. My claim to fail fame? The simulations. Do not sleep on these. Work through tons of them in your study program because if you can't get through the SIMS during studying, you are likely not ready for the test.
I also failed AUD again. Second time taking it, and I would be done if I had passed it. I knew it would be close… it was a tough exam. Definitely sad and frustrated, but everyone's posts have lifted my spirits. I know I can hit those SIMs harder this time, and I can finally pass this thing!
