Failed AUD back in early August with a 71. I used Yaeger lectures and the Wiley Book from 2014. Having old materials messed me up a little for this exam. Purchased updated copies of the Wiley Book and Wiley Focus Notes and went to town. It was so much better studying on the computer than flipping back-and-forth through a book. I waited almost 4 months to get started again. Knocked out BEC in that time frame but just couldn't bring myself to get cracking on AUD until 8 days before the exam. Over those 8 days, I put in about 90 hours of studying and it paid off. 79, woohoo!
It's funny with the retake because certain topics I got hammered on for test 1 barely appeared during test 2. Yeah, certain test themes are the same but the odds-and-ends have so much variance. As soon as I get out of every test, I write down as much as possible about the exam in case I have to take it again. Those AUD questions sure are tricky. Good riddance AUD! REG, here I come.
