I have launched a self-paced course that people can take at any time (no start or end dates). It is also ungraded. I do have modules that are set as prerequisites and parts of the modules are set as requirements. Many students have already started or are taking the course. If I add new files to those modules, will that mess up their progress / be read by Canvas as if they didn't complete the module and reset that they already completed a prerequisite module or required part of a module? If yes, do they simply need to go in an open the file in order to re-unlock the other modules? AND will what they already completed in those other modules be re-set or will it be read as if they completed it? I don't want to inadvertently lock anyone out from being able to go back to resources in modules they have already completed. Thank you!
