For the person who asked about CPAexcel, I'm using it. I passed REG with a 78. I thought CPAexcel prepared me for it, I'm just not very good at tax and the REG Sims were so random (plus it was my first section I took). I suggest using the CPAreviewforfree.com website also (they have a ton of MCQ for free on there), and the MCQ are free so you don't have to pay for that. Good luck on REG.
Come on AUD scores!!!
REG - 78
BEC - 88
