By the time you’re preparing to take your first proctored exam, you should have already completed the Proctoring Orientation module in your course, created an Examity profile, and taken a practice exam.
When it's time to take a proctored exam, you'll always start from inside your Canvas course.
Next, you'll select the Examity Authorization link in your course.
Then, in Examity, locate the exam you want to take and follow the instructions.
