The main reason for the high duplicate checking rate of many college students' graduation thesis is that there are too many quotations, so it is the primary task of college students to modify the contents of quotations. College graduates can reduce the repetition of quotations by modifying the word order of quotations, replacing keywords with synonyms, and adding modifiers appropriately.

2. Picture replacement

Picture replacement is a direct method to reduce the weight of graduation thesis, mainly because most thesis detection systems are not perfect at this stage. College students can take advantage of this, without affecting the overall idea of graduation thesis, and display the duplicate data in the thesis by using picture screenshots, which directly avoids the detection of this part by the paper duplicate checking system and reduces the duplicate checking rate of the thesis.

3. Format modification

Most duplicate checking systems in society classify the contents of papers according to their formats, which are mainly divided into two categories: those that need data comparison and those that don't. The main reason for the high duplicate checking rate of many college students' graduation thesis is that the paper format is incorrect, which leads to the paper detection system unable to correctly identify the format, and the content that needs data comparison increases greatly, which leads to the high duplicate checking rate of the paper. Therefore, many college graduates must check whether their papers are in the correct format when they find that how to modify the duplicate checking rate of papers is not up to the standard, so as to reduce the duplicate checking rate of papers.
