[I might need to get different screenshots of a submitted HW assignment in the Grade Center - the only attempt I have on my BB test course is for an assignment I created using the test banks]

Late Homework assignment submissions on Blackboard must be recorded manually from the Grade Center for the course.

Navigate to the Grade Center and select the View Grade Details option next to the late submission.

Click on the Manual Override option.

On the following screen you can factor the Late Penalty into the student's Override Grade, and Feedback to Learner or Grading Notes for your records.

Once you click on Save, you will see a banner message appear about the Manual Override being successful, as well as the new grade next to a message that says "Original grade has been overridden."
