A large majority of students take exams in our designated testing centers and will be using Canvas this coming semester to take their exams. We have this set up with our Testing Center with the IP addresses for the computers, but we have come to the realization that students still have access to the Inbox feature while taking an exam. This is alarming, because this would be a very easy way for students to share quiz or test answers. In addition, they can access their Files in the "Account" area. We use a lock-down browser for these exams (normally midterms and finals), so is there some customization available to disable the global navigation menu, or areas of that menu for specific IP addresses? If not, are there work arounds you propose to prevent file sharing and conversations when students are taking an exam or quiz?
