Publicly shared class IDs are almost always configured to store papers. If you upload your draft to one of these classes, . When your actual professor scans your final paper a few days later, Turnitin will flag it as 100% plagiarized against your own previous submission. Proving to your university that you were the original author of the leaked submission is incredibly difficult. 2. Instructors See Everything You Upload
Turnitin does not sell individual subscriptions to students. The platform operates strictly on an institutional model, selling licenses directly to schools, colleges, and universities.
Instructors sometimes create test classes with no students. If the enrollment key becomes known publicly, outsiders can join. These classes are often deleted quickly.
For institutions using Google Workspace for Education, Turnitin Draft Coach provides students with grammar, citation, and similarity feedback visible only to them before final submission. Draft Coach allows legitimate, instructor-approved pre-submission checking without violating any policies.
