The requirement of repetition rate of undergraduate thesis generally varies with different schools, majors and thesis types. Generally speaking, most colleges and universities require the duplicate checking rate of undergraduate thesis to be 25%, and some 985/2 1 1 undergraduate colleges require the duplicate checking rate of undergraduate thesis to be less than 20%.

Specifically, if the repetition rate of the whole document is less than 9% and the repetition rate of paragraphs is less than 20%, such a paper can pass the duplicate check directly, and the duplicate check rate of the paper is qualified. If the total repetition rate of the full text of undergraduate thesis is 30%~35% and the total repetition rate of paragraphs is 40%, then there are some problems of repetition and similarity in the thesis. This part of the paper will be revised by the instructor and reviewed normally after revision. If the total repetition rate of undergraduate thesis is 35%~45% and the repetition rate of paragraphs is 40%~55%, it is likely to be judged as moderate plagiarism. The school will feedback the duplicate checking rate of undergraduate thesis to the tutor, and then the tutor will guide the students to make corrections within one week, and then they can pass the duplicate checking again.

It should be noted that these are general instructions, and different schools and colleges may have their own regulations and requirements. Therefore, graduates need to abide by the regulations of their own schools and colleges and try to avoid repetition in their papers to ensure their independence and originality.
