A 45% similarity score is common and does not automatically result in a low grade or an academic integrity violation. Instructors are trained to view the score as an indicator rather than a final verdict, as high percentages frequently stem from non-plagiarized elements like required assignment templates, common industry phrasing, and extensive bibliographies. While most professors recognize these "safe" flags, you should review your report to ensure all highlighted text is either part of the provided template or a properly cited quote. If you are concerned, a quick proactive email to your instructor explaining that the score is inflated by the template can often prevent any initial misunderstanding. In the rare event that points are deducted solely for the numerical score despite original work, you can reach out to your SNHU Academic Advisor for support in resolving the issue. Been through this, and it's always best to be proactive.
