Under 'My Classes', click on a project
Project sections that are ready for review will be marked with a pencil icon
To review the section, click on it
Review the section and leave feedback for the student as a comment below the section, if needed
If you'd like the student to keep working, select the 'BACK TO DRAFT' button to send the section back to the draft state
If you're happy with the student's work, click on the 'COMPLETED' button to mark the section as complete. Marking a section as complete will make it uneditable and finalized. Note that as a teacher, you can undo this action.
