You can save your current grading progress (and associated audio, video, or rubric feedback) by tapping Save Draft in the grading panel.
Save Draft vs. Send Grade
Because instructors often do not complete an entire grading cycle or grade all submissions for an assignment in one session, they may not want to provide only a subset of grades for a given assignment.
To accommodate this use case, Bb Grader does not automatically sync grades entered within the app with the Blackboard Learn Grade Center when you tap Save Draft. Instead, you can send all grades at once to the Grade Center from the Submissions List page by tapping Send Graded located in the upper right-hand corner.
However, instructors are able to selectively release individual grades to the Learn Grade Center by tapping the Send Grade button in the upper-right hand corner of the grading panel.
