AUD's not as bad as FAR or REG, but harder than BEC. 

So, the worst part is over.  The AUD section is also way more verbal focused than the others.  So you need to focus on what angles the questions are coming from to try and trick you.  You will see recurring themes in their trickery, you just have to out-trick the trickster.  keep with it, and you will see right through their lies.

Here is a controversial topic:

I'm generally not a fan of memorization, because you need to understand everything, not just memorize lists.  BUT, I do recommend breaking out the basic Audit Report and writing it out verbatim on 3 flashcards.  1 per paragraph.  MEMORIZE this report and it will help with SO many questions, because a lot of stuff is just variations of that report.  It took me like 30 minutes one day to completely memorize it, and I'd just recite it to myself every 3 days or so to make sure I still had it.  It's worth it because it can help with so many questions.
