Plagiarism is a question of attribution and authorship, not a permitted percentage. A similarity tool can identify matches but cannot decide the context of every one.
A practical starting point
Inspect matched passages and citations alongside the institution’s policy. Do not remove valid attribution just to lower a score.
Understand the task
There is no safe percentage of plagiarism. A similarity report identifies text matches; it does not decide whether the work is properly attributed. A low score can still conceal an uncited idea, while a higher score may include quotations and references.
Develop the reasoning
Keep a record of which notes are quotations and which are your summaries. Add citations as you draft so that source material does not become detached from its origin. Credit ideas, data and distinctive arguments as well as exact wording.
Use evidence carefully
Paraphrasing means explaining a source in a new structure for your own argument. Changing a few words is not enough. Compare your draft with the original to check accuracy, then supply the citation required by the course.
Review the finished work
Follow your institution’s rules for collaboration, outside assistance and writing tools. If the permitted boundary is unclear, ask the course team before submitting. Keep drafts and research notes that show how your work developed.
Before you submit
- Check the brief and marking criteria for this task.
- Confirm the source and date of each factual claim.
- Review the argument before making the final language checks.
- Keep the final file and any submission confirmation.
