My first audit, I got a 74, felt there was no way made over a 60. 74 was as pleasant of a surprise as it could have been, since it was obviously a failure.
Second time, I just reinforced everything, felt like I had passed based on my feeling of the first try. Made a 72, even though from my score report, I scored stronger in all but one area of mcq, while in the first time, I got one stronger, one weaker and the rest were comparable. I couldn't find the research at all and the sims were brutal that time.
Third time, I studied less than the other two, but I changed it up. I started doing my FAR lectures (which really helped me, FAR type sims were killing me). I actually ditched Ninja for this one. I had a friend give me a pdf of Becker questions. I did them all once and made notes of what I missed. I had Gleim from an MBA class I took, I used it, I ditched Gleim for Ninja from my REG MBA class as Gleim REG is unrealistically hard. I also used CPAReviewForFree.com, those questions helped a whole lot. Then the biggest thing that happened was simply I got questions I knew.
But going through and writing notes, I realized what I thought I knew wasn't what I actually knew. For instance, I knew what control risk, detection risk, and inherent risk was, but I didn't how a specific transaction or event effected those events specifically. I read my notes in the parking lot at Prometric before I went in (only about 10 pages of notebook writing, so not much), and reading my notes on that subject really helped me.
Now Ninja notes are great, but make your own for what you are not good at. Ninja notes are a general note for everybody. Everybody is different, you have to make some for stuff that you don't understand.
