Strategically planning tests during the 18-month period in which a candidate must pass all sections is key to a successful CPA Exam schedule. That means giving close attention to the testing windows when the CPA Exam is offered as well as coordinating tests with score release timetables. Using the score release timetables will help in organizing a review of test material and planning testing schedules. Once you receive your CPA Exam Notice to Schedule, you have a limited amount of time to schedule the day and time of your exam(s) based on the expiration date listed on your NTS. Candidates are not allowed to take the same section more than once during any single testing window. They may take all four sections of the exam during any one testing window. Coordination is important because candidates who don’t pass all four sections within 18 months lose credit for the first part passed, and they must begin the entire process again. Starting with the section you find the most difficult gives you an edge in scheduling, because the 18-month rolling window only begins once you’ve passed your first section.
