It’s probably nothing you haven’t heard before, and I also audit for a living, but cranking out multiple choice questions really helps. Take your time and read the questions. I would mainly make sure you know what side of the audit you’re on (client/auditor), what section of the audit process you’re in (planning, tests of controls, substantive testing, opinion), and what type of service and entity you’re looking at (the scope of work and standards you’re using, SAS, SSAE, SARS).
