sometimes when giving tests and quizzes you would like to lock browsers so that students cannot search for answers beyond Safe Browser. To set it up click on three dots by the quiz and then on Edit Settings:
Then scroll down until you see the Safe Exam Browser area and select Yes-Configure manually from the drop-down menu:
It will add a menu for students to let them know that the test/quiz requires Safe Exam Browser (ignore Download configuration):
Students then will be prompted to Download Safe Exam Browser and should ignore any other options. They will only have to do it once and after that they will just have to click on Launch Safe Exam Browser.
