First of all, you can communicate with the college or tutor to explain why the paper exceeds the word limit. If the content of the paper really needs so many words to be fully presented, the college or tutor is likely to understand and support the author.
Secondly, the paper can be simplified and some irrelevant contents can be deleted, so that the number of words in the paper can meet the requirements of the duplicate checking system. In the process of streamlining, we should filter according to the key points and core ideas of the paper and keep the most critical parts. At the same time, it is necessary to ensure that the structure and logic of the simplified paper are complete and will not affect readers' understanding of the content of the paper.
In addition, some contents can be transferred to the appendix. Appendix is a part of the paper, which is used to include some contents related to the main content but not the core. The author can put some detailed data, charts or other details in the appendix, so that even if the paper exceeds the word limit, the duplicate checking system will not calculate it. At the same time, when quoting the appendix in the paper, the author needs to mention the specific page number or appendix number for the convenience of readers.
