Setting up Assignment and Quiz Importing

First define an attendance status that should indicate an on time status. Late submissions can use the same status if you do not wish to differnetiate between them, otherwise a seperate late status can be defined.

If a late submission should not be awarded any value, simply setup an attendance status for it that has a value of 0.
