A student must fix his assignment. Should I Revert the submission to draftor Allow another attempt?
If after checking his submission, you want the student to fix it, you can either Revert the submission to draft or Allow another attempt (either in the Edit dropdown menu or the link* on the View/grade all submissions page). Allow another attempt saves the existing attempt together with its feedback and allows the student to submit another attempt which will have its own feedback.
Revert the submission to draft preserves the feedback but effectively deletes any record of the fact that he has already submitted. Note: In order to allow another attempt, the assignment's Maximum attempts must be greater than his number of attempts so far.
If you Revert the submission to draft or Allow another attempt , you may want to Grant extension (either in the Edit dropdown menu or the link* on the View/grade all submissions page). If you Revert the submission to draft, you will probably want to make a note of the fact that you have done so (in the Feedback, possibly). Note : If you Allow another attempt, the status is changed to Reopened, rather than Draft (not submitted).
