3 weeks till AUD – too late for supplemental?

I can't speak to AUD, but I usually add supplemental materials towards the end of my study window (REG 2 weeks before the exam; FAR 4 weeks before; BEC 3 weeks before). I prefer adding Ninja MCQ even if I'm only 30% through the Becker MCQs because it's ‘fresh'. Even if I've done 300 Becker MCQs and have 1,000 left I prefer to supplement for a change of pace and sometimes the topic/terminology is slightly different and you get a better feel for what to expect. Also, it's not that expensive in the scheme of what we're hoping to achieve here.

I've never taken AUD so I can't speak for that exam specifically, however I can say that I believe Ninja really has helped me more thoroughly understand the material. My first go around with FAR, I used Wiley CPA EXCEL and WTB and I learned what a lot of answers to questions were because “that's just the right answer.” Ninja has helped me actually understand why answers are right and why others are wrong. The related term definitions and references included within each answer explanation help solidify knowledge on topics you may not fully understand beforehand. I think 3 weeks is plenty of time to use it as a supplement. You may not be able to get through all the questions, but do custom sets of new questions only each time so you don't get repeats. This way you will review as may topics as possible. One again, I am not positive if AUD is the same way, but I also found Ninja Simulations to be much more similar to the actual exam than Wiley. They give me curve balls to wall through like the actual exam did, and I appreciate it!
