Your pdf document MUST be completely uploaded by the deadline. The deadline is electronically set and it is not subject to interpretation (it is absolute). Unless the Canvas servers reportedly malfunction, technical issues at the user end (slow internet, scanner not working, computer crash, etc.) are personal issues and will not be accommodated.   Keep in mind that uploading your file will take time. Also, Canvas might log you out, if it sits idle while you take your exam.

You are responsible for meeting the deadline. If you miss it, you missed it!
