I too did not memorize all of them. It seems like if someone sneezed they made a mnemonic for it. You start to forget which mnemonic goes with what topic. Look at the ones that cover topics you feel weak in or strike you as important. I went with internal controls, evidence testing (forget now, but it was a long one on the different types of tests such as vouch, trace, etc).
AUD was my first section as well and I also used Becker. The key to my success was really doing the MC questions over and over and over again. If your eyes start to bleed from doing the MC questions so much you are getting close. When doing the questions don't just look for the correct answer. Before looking at the answer identify which concept they are testing, what the correct answer is, why the wrong answers are wrong, and then think of how they could ask a question a different way. If you do that and can score in the 85-90% range on all the various question sets you should be in great shape. The above is how I used the Becker materials and I scored 94 on the actual test.
In addition, I would spend some time and make sure you know/understand/memorize that funky chart they draw in one of the latter classes dealing with audit tests. I'm thinking of the chart that includes the client's inventory, records, the auditors sample count. The chart has the arrows coming and going to the different areas and discusses vouching and tracing. That was a goofy chart and was a bit confusing. Spend some time on it and listen to the lecture again until you understand it. There are many questions that can be derived from those concepts and can net you several points on the exam.
The practice final exams in Becker were good. They were harder than my actual exam but felt to be a good match. Don't skimp on the supplemental questions. There are a ton of them but spend the time and do them. They ask questions in different ways than the regular questions and seeing the questions asked in different ways will help you think through the actual exam questions.
