Turnitin is a tool that identifies levels of similarity between your writing and other student assignments and published work.
All written assignments submitted online at UniSA are submitted to Turnitin. In some courses this is only done once the assignment is officially submitted. However, in many courses you can submit your work ahead of the deadline to generate your own Orginality report. This enables you to check how similar your work is to other sources. You can then withdraw the assignment to make any necessary changes and resubmit it in revised form. Ask your course coordinator if you're unsure whether this applies to you.
