Recently, there have been a number of issues surrounding the ‘PDF submission’ type within the ‘Assignment’ activity in cuLearn. We would like to advise against using this type of assignment submission, and instead, only use ‘File submission’ type. Students can still upload PDFs with the regular file submission type, so there will be no real loss in functionality. Learn more about creating assignments in cuLearn where students can upload their work
