Feedback Studio for iPad supports multiple roles! As an instructor, you can mark and grade your students' submissions, and as a student, you can submit papers to your assignments and view instructor feedback all from the same app.
So that you can view the classes you are enrolled in as a student alongside the classes you've created as an instructor, you must be using the same email address for both roles.
...we will show only the instructor view in this instance, as we can only support one user type per individual class. In order to access the student view of this class, you must access the desktop version of Turnitin.
