Why is my similarity score 100%?
Answer
One reason that a student might receive a similarity score of 100 is that they are self matching. This can occur if a student has already submitted the exact paper to a different class although if the student submits the same paper to multiple assignments in the same class then it should not show as a match.
For more information on how a self match can occur view this Turnitin article.
