I just took AUD on April 7th. Started studying at the very end of January (It's more than enough time, I just like to leave myself plenty of time). I used primarily Becker and Ninja MCQ in my last couple of weeks. Ninja is an amazing review tool, I haven't used it as a primary source. For Becker, I listened to lectures in my car, then did MCQ, Skills Practice and SIMS. I try to read the book after I have done all that as well. If not, I re-read the book during my review. In the last 3 weeks, I went through the text, made my own notes, more flashcards, and went through the entire Ninja testbank for MCQ and SIMS. I also did Becker Progress Tests in different combinations of chapters on a daily basis. I studied about 3 hours on a weekday and anywhere from 3-6 hours on the weekend, but not every weekend, as I have family obligations.
