I'm translating some labels and messages of a web system to English. In the context of learning, there are activities that must be finished on a specific date, like in a classroom with teachers and students. I want to know the word teachers usually use to define a task that is finished behind schedule, is it ok to use "overdue"?
The word that is usually used in a school setting is "late." "Overdue" implies something more along the lines of a library book, not a school assignment.
If you turn assignments in late, you lose ten percent of your grade for each day it is late.
I finished the essay last night, but since I turned it in after midnight, it was late.
Late: occurring, coming, or being after the usual or proper time
