Security - settings
The security settings offer a number of choices. Start by deciding if the exam should be written with Safe Exam Browser (1), locking students computers during the exam. Safe Exam Browser is primarily intended for use during supervised examinations. Also allow Inspera Lockdown for Cromebooks (2).
If you want student submissions to undergo plagiarism review in Ouriginal, click Request Similarity report (3).
Under Advanced settings (4), you can allow students to change WiFi during the test, which is a good idea to do.
