To submit assignments in Sullivan Blackboard, log in to your Blackboard account, open your course, and go to the “Assignments” or “Course Content” section. Click on the assignment you need to submit, then hit “Browse Local Files” (or similar) to upload your file. Once uploaded, click “Submit” and wait for the confirmation message. Don’t skip this part, or it won’t count. I usually double-check by reopening the assignment to see if my file is attached properly.
