Why hand in at all
From the adviser's side, a gradebook that has stopped changing could be finished or could be abandoned — the numbers look the same. Mark as done is the difference: it says this period is what you meant to hand in.
Handing in
On the class record, pick the grading period and press Mark as done. Two things happen:
- The adviser's class overview shows the period as Handed in under your subject, with your name and the date.
- The period closes to change — scores, adjustments and activities in it refuse edits until it is reopened. What the adviser reads stays what you handed in.
Grades and conduct are handed in separately: the conduct sheet has its own Mark as done, and finishing one says nothing about the other.
Reopening
Either you or the class's adviser can reopen a handed-in period — nobody is locked out of a correction — and both the hand-in and the reopening are audit-logged. Reopen, fix the score, and mark it done again; the overview shows the newer hand-in.
What it is not
Handing in is a signal between teachers, not a release. Learners see nothing when you mark a period done; report cards move only when the adviser releases the term, and the release pre-flight is unchanged either way.
