@hopeful,
I'm sorry to hear the bad news. 🙁 You came really close to passing both AUD and REG, so you're on the right track. If it were me, I'd retake them taking only one per window, so that I could really focus on each section. Give each one your all so that this next time will be the last time you ever have to take these sections.
As far as Becker goes, I'll give you my recommendations, but keep in mind that we may have different learning styles.
Skip the lectures (unless you get a lot out of them).
Read each section in the book, including the ancillary info. Don't spend much time on the ancillary info, but do read it over once.
Take comprehensive notes while you read through each section. Really try to understand the concepts, and mark information that needs to be memorized.
After you read through and take notes on a section, do all of the MC for it. Add key points from the answer explanations to your notes if you don't already have them in there.
Once you're done going through each of the sections and doing the MCs, do all of the supplemental MCs.
After you get through all of the chapters once, go back through them once more, focusing primarily on your notes, and then redo the MC. Mark any MC that you miss so that you can do them a third time.
Don't spend too much time on the sims, but do look at the solutions and make sure that you understand the concepts that are being tested.
If you have time, consider supplementing Becker with a test bank from Wiley, Gleim, etc.; if not, just focus on Becker.
I hope this helps, and good luck to you!
AUD - 95, BEC - 85
