Wiley’s CPA Exam Review is published twice a year in two formats for your convenience and choice: a two-volume set and a four-volume set, with all volumes also available individually. The four-volume set matches the four-test structure of the CPA exam, so you can choose only the volumes you need for your upcoming tests. Or you can pick the two-volume set, which separates study outlines, guidelines and tips into the first volume and collects practice questions and solutions in the second volume. Choose by structure or by date — the four-volume set is published each December and the two-volume set each June, so you can always be assured of up-to-date test information and questions.
