The CSM certification exam consists of 50 questions. You will have one hour to finish it, aiming for a passing score of 74% (37 correct answers). The test is an open book, allowing you to refer to the Scrum Guide, course handout, and your notes from the course. Make sure to complete the exam within 90 days after taking the Scrum Master certificate course. If you accidentally close the exam window, you can reopen it immediately.
