This article explains options instructors have to deal with late completed work.
Did you miss the due date?
If your instructor has enabled late submissions for the assignment, you may upload a submission after the deadline (but before the late deadline).
If you were not able to submit an assignment before the late submissions deadline, or if late submissions are not enabled for your assignment, please contact your TA or instructor. They can manually upload a submission for you after the deadline if they wish to allow it. The UIC LTS and Gradescope teams cannot make course policy decisions on their behalf.
Note: Late submissions may be subject to penalties, as determined by your instructor.
