Sadly, I'm not one of those who passed audit yet, BUT I took it recently...and all I can say is that it was much harder this time around than it was last time.
Last time, I had majority of MCQs that were very very similar, if not exact that were in Becker passmaster. SIMS weren't too bad, and totally doable (minus the J/Es.). I have no idea why I didn't pass:(
This time around, I had about 10-15 MCQs that were similar to Becker, a lot was similar but there were many hard questions. Couple that I didn't even see in my review. I also had one or two IFRS questions in each testlet. SIMS were hard and def. tested my knowledge.
So my advice is to read each chapter in Becker, do all the MCQs at least three times. Don't scan over IFRS stuff and hope you have luck on your side. Last time, I got very lucky...but I wasn't as prepared. This time, I was, but luck wasn't haha. It's totally doable in 28 days, and you will DO it. Good Luck!
