When I was studying, I would do the lecture, skills practice, and then MC in a row, or maybe the next lecture and then go back to the previous MC. I would skip the sims until my final review for the exam. I would take a progress test every week or so while learning the material to kind of keep stuff fresh, only about 20 questions until I got to my final review.
For my final review, I would re-skim every chapter and mark pages that had important info I might want to glance at once more before the exam. After each chapter, I would do the sims for that chapter. Once I got done with reviewing all of the chapters and completing all of the sims, then I would take the first mock exam. I would also track the percentage I was getting correct on the sims to gauge my understanding of that chapter. After my first mock exam, I would thoroughly review the whole exam and then hammer progress tests until I was ready to take my 2nd mock exam. I usually took my first mock about 6 days out, and the 2nd mock about 3-4 days out. Don't forget to do the AICPA released questions, and the mini mock exam the AICPA puts out.
In terms of the progress tests, I would come across the same questions due to the number of tests I was taking. By exam day, I usually had taken about 20-25 progress tests. I would do a progress test for each individual chapter, probably 15-20 questions, then transition to doing two chapters in one test, but still about 15-20 questions. Overall, I tried to get at least 8 questions for each chapter into a progress test, so if it was 3 chapters, I would do 24 questions. After my 2nd mock exam, I would only take progress tests with the exact amount of questions you'd see in a module on the actual exam to get my mind ready for what to expect, and I would do two back to back to imitate the exam.
For AUD specifically, I was also averaging 85-90% on the progress tests and seeing the same questions multiple times, but I honestly thought the MC on the AUD exam was a breeze, and it wasn't as inconclusive as Becker's questions were. I had time to finish the module and do a thorough review of each question for all of the AUD multiple choice. This wasn't the case with any of the other exams, I would only have time for a quick skim review of each question.
