C0. Updated version of Canvas files

Updated Canvas document might be located here (eg Webex Meeting info). Originals appear in Canvas/Announcements or Canvas/Modules. Canvas has synchronization issues, so a document posted in Canvas will never be updated. Updated Canvas documents will be made available in this section. Canvas has synchronization problems when a document gets updated. If NJIT declares an emergency an in class exam might become an online exam. In that contingency the online exam would be in Canvas using proctoring from ProctorU Record+ (previously known as Review+). This is different from ProctorU Live+ that requires to book an appointment (with a live proctor) with ProctorU. Hopefully things will move smoothly and there would be no emergency! This explains the two ProctorU related links below.
