You can simultaneously view additional notebooks and download a notebook or several notebooks as PDF files as follows:

When you're on the grading screen, click the "Eye" button on the toolbar



A new tab will open in the browser where you will see the current exam notebook. In this tab, the exam notebook can be downloaded as a PDF file to the computer or print it



You can also choose to view additional notebooks associated with the course by using the selection menu. 
The file download and print operation can be performed on any selected notebook


What does the final file, delivered to the students, look like?

If we use the "Eye" button in a notebook in which we approved its final grade, the file that will be presented in the new tab will be the file that the student will receive (including the score table, remarks and the score annotations)
