Q. I would like to set up a mostly essay test, where the student answers several questions and then attaches a pdf of the article they are reviewing. It appears that there is a way to allow the student to attach a pdf to the test, however when I try to do this it does not seem to be working. Please advise.
A. Instead of adding an Essay question to the test, add the one right below it in the list: a File Response question. That will allow students to reply with an attachment.
Also, make sure that in Test Question Settings you have checked the box for “Add images, files, and external links to answers.”
