Why is my Turnitin similarity score so high on a college essay?

Your Turnitin similarity score is high because the system flags not only exact quotations but also any phrasing that closely matches sources, including common literary language, paraphrased sentences, and even your bibliography; it also counts the novel’s quoted lines and any standard essay structure that appears in other students’ work. Turnitin’s algorithm looks for strings of words that appear elsewhere, so even well‑intended paraphrases can trigger matches if they retain the original sentence pattern or use distinctive wording from the source. In a personal statement, the “voice” you’re trying to convey often overlaps with the style of the novel you’re discussing, and the MLA citation format itself is a repeated pattern that contributes to the total percentage. The most effective way to lower the score is to rewrite the flagged sections in your own words while preserving the meaning, and to limit direct quotations to the absolute minimum required. Start by pulling the Turnitin report to see which passages are highlighted; for each, ask yourself whether you can express the idea using a different sentence structure or simpler language. For example, if a sentence mirrors a line from the novel, replace it with a brief summary of the scene and then add a citation for the idea rather than the exact wording. This reduces the overlap because the wording becomes uniquely yours, and the citation still gives credit. Also, double‑check that your bibliography and any standard headings aren’t being counted as matches; sometimes removing extra spaces or reformatting can shave a few points. By systematically rephrasing and trimming quoted material, you’ll bring the similarity below the 15% threshold while keeping the essay authentic and properly credited.
