In no particular order:
(1) know what is on the reports–compilations, reviews, agreed upon procedures, significant deficiencies and material weaknesses, the various audit reports.
(2) know COLD the definitions of differences between $ubtantive procedures and internal control activities. Often, you can narrow down the choices of multiple guess questions by evaluating the answer choices. eg This helps with most sampling questions.
(3) Closely related to (2), keep in mind what engagement you are being asked about. Reviews do not involve outside contact–you wouldn't normally contact outside counsel of the client like you would for an audit. Likewise, you don't test or weigh evidence in a review engagement.
(4) Go over the various cycles–revenue, A/R, Purchases, Inventory, and Payroll. I would pull out your textbook from your audit class. Sketch out each cycle and the control functions. Then go over SIMs on them. NINJA has some excellent ones.
(5) For all four sections, not just AUD, comb over the AICPA recently released questions. If you're a NINJA, Jeff includes with MCQ two sets, moderate and difficult for the last two years. Save this last step for when you are within one week of the exam. Don't panic if you do more poorly than you expected on the recently released MCQ. It'll act as a tune-up and at the very least expose you to newER questions.

Also don't panic. Whenever I felt tense, I just counted to 10, took a deep breath after each number, and reminded myself that I will be fine because I prepared.
Insert Stewart Smalley joke here.

These steps should carry you through.
