1. Navigate to the assignment dashboard you'd like to change by clicking the assignment and the class.
2. Once on the dashboard, scroll down to the student roster and find the student whose submission you need to review.
3. Click on the 'Last graded...' link by the student's name.
4. Find your review on the right of the student's writing and click 'Edit'. Then, click 'Continue'.
5. Make all of the appropriate changes to your previous review and click 'Submit' when you are done.
❗NOTE: If you are changing your review after a student has already revised their work based on that review, the student will not see your new comments. However, they will see the percent or points they received from you change to reflect your latest edits.
