I am using the Quiz: Essay option for timed "take-home" exams. I have found a way to download all the response files (pdf) to grade, but there doesn't seem a way to upload the graded files, unlike the Assignment module.
Does anybody know how to get around this?
ps. Some have suggested using the Assignment module instead but as far as I can tell, this module does not allow me to set a time limit (that is, once student accesses exam, they have only X minutes to complete).
