You can submit a homework question for marking using the assignments tool inside your course on MyKaplan. To access the assignments tool, go to your course and click 'Assignments' in the navigation bar at the top. Your tutor will have set up an Assignments submission folder for the specific homework question. Go to this folder and click 'upload' to add your answer to the Dropbox for your tutor to mark. Once marked, you can also access your grade/tutor comments on your submission from here.
