Some of my students handed in their answers offline on a USB device. How do I grade the answers in the offline answer file?

The offline answer file on a USB device contains the students answers and cannot be graded in its current state. Instead, go to the examination that the offline answer file belongs to in your teacher account in Digiexam. You can then upload the offline answer file to the examination by clicking the "Upload offline answer file" button.
