What a regrade does in Moodle

Once a question is corrected, earlier attempts still carry the old marks until you run a moodle quiz regrade.

Regrade after changing scoring-relevant parts, such as correct answers or marks.
Wording fixes that keep the same answer usually need no regrade.
Students' submitted responses stay the same; only their scores are recalculated.
Keep a copy of the old quiz so you can compare scores before and after the regrade.

Example Moodle regrade questions

After you change a question's correct answer in a quiz with attempts, what must you do?Run a regrade so existing attempts are rescored with the new answer key, because otherwise students keep the old marks.

Does a regrade alter the responses students submitted?No. It recalculates scores from the saved responses using the current question settings, so the answers stay as submitted.

Is a regrade needed after fixing a typo in question text only?Usually not. Scoring depends on the answer key and marks, so wording-only edits that keep the same answer don't change grades.

Why keep a copy of the quiz before editing it?It lets you compare scores before and after the regrade, which shows whether the changes affected only the intended questions.

What happens to attempt totals when you change a question's point value and regrade?Totals are recalculated against the new point value, so the gradebook matches the current quiz settings.

Generate the full set

Questions from your material

Upload PDFs, slides, DOCX files, notes or photos of pages, and get multiple-choice, true/false or open questions.

Explanations included

Each generated question comes with an explanation, so the corrected version teaches the reason behind the answer.

Moodle XML export

The Pro plan exports Moodle XML, along with QTI 2.1, so rebuilt questions can be imported into your course.

How it works

Upload your source

Add the lecture slides, notes or textbook pages the quiz was based on.

Generate corrected questions

Create a fresh question set with answers and explanations that match the corrected key.

Export and regrade in Moodle

Export Moodle XML on Pro, import it, then run the regrade inside Moodle to update attempts.

Regrading happens inside Moodle, not in DeckOwl. DeckOwl does not touch your course or gradebook; it helps when the fix means rewriting questions from your own notes, which you can export as Moodle XML.

Wording-only edits that keep the same answer usually don't change scoring, so no regrade is needed in that case. Changes to the correct answer or the marks per question do call for one, so existing attempts match the corrected key.
