We are actually pretty flexible on when you can take the exam, as long as it is within the set Exam Windows. During the preparatory portion of the exams, leading up to the Exam window itself, we do encourage our students to plan ahead and have time set aside in their schedule for the exam itself.
Your exam will take place online via an automated exam tool. It is a two-hour, open-book test which includes a mixture of fill-in-the-blank and detailed discussion questions. You may choose for yourself the specific day and time to complete the exam during the exam window. There are three Exam windows offered during the year, and you can see the dates (these remain the same from year to year for ease of planning) here: https://schoolafm.com/certification/
