Consult a tutor: seek the help and guidance of a tutor. Explain the situation to them and ask for their suggestions and opinions. They may provide guidance to solve the problem and help you make appropriate corrections.
In-depth study and rewriting: for the plagiarized part, conduct in-depth study, re-understand the relevant content, and re-express it in your own words. Make sure that the rewritten content is original and follow the correct citation format when quoting.
Use the paper duplicate checking tool: after the paper is revised and rewritten, use a professional duplicate checking tool, such as paperfree, to check the originality of the content. These tools can help you identify whether there are other undiscovered plagiarism problems to ensure the quality of the final paper.
