First off, a Turnitin originality report is not something to pass or fail – it is merely a tool to guide you and your tutor. The percentage score is dependent on the settings your tutor has used. A high score can actually mean that your references are extensive.
As a tutor, here is the guidance on how to set up Turnitin submission point correctly. If you would like to know more on " how to read Turnitin similarity report", please have a read this blog post.
For those students, a similarity score is 0% this may mean that your work is something a little non-standard (like a presentation) or your tutor has used fairly permissive settings.
A score of 100% normally indicates that you have submitted your work to another NILE module by mistake. Please make your marking tutor aware of this – they can check what has happened and exclude any matches to your other submission. Submitting two assignments to the same module and course (for example a draft and final version) won’t match each other though.
If you have any questions about your originality score, you should discuss these with your tutor.
