If you don't pursue excellent papers, the duplicate checking rate can meet the repetition rate requirements of the duplicate checking system stipulated by the school. Each school has different requirements for the specific duplicate checking rate, which is generally below 30% for undergraduate students and below 15% for postgraduate papers. If you use other duplicate checking websites before the paper is finalized, try to reduce the repetition rate of the paper to less than twice that required by the school. Generally speaking, the graduation thesis of college students is handed over to the tutor. After the school has passed the examination, the content and structure will be tested by software. Software testing varies from school to school.
The general criteria for defining plagiarism are: "the repetition rate of undergraduate thesis is less than 20%, that of specialized thesis is less than 30%, that of master thesis is less than 10%, and that of doctoral thesis is less than 5%", but this is only a benchmark. Because the strictness and system of each school are different, especially in recent years, the duplicate checking rate of Zhai Tianlin's doctoral thesis is above 40%, and the original rate of the thesis is even stricter. Many colleges and universities explicitly require that the repetition rate of papers be controlled within 10%, and even the repetition rate of 5% is nothing new. By setting the repetition rate, the school is also telling students to pay attention to originality and not to copy.
