The results of duplicate checking and random sampling of undergraduate graduation thesis can generally be obtained within 24-48 hours after submission, but the actual time consumption will vary due to many factors such as schools, the number of words in the thesis, the sampling method of the thesis and so on.

First of all, different sampling methods in schools will affect the time-consuming sampling inspection. Some schools will adopt online sampling, which takes less time and results faster than offline sampling.

However, some schools still use offline sampling, which will take longer to check the repeated sampling. Students are required to mail the original test paper to the school, and then the school will send someone to conduct offline sampling inspection, and finally feedback the sampling results to the students.

Secondly, the number of words in the paper will also affect the sampling time. Generally speaking, the longer the paper, the longer the sampling results come out.

In the case of school online sampling, a long paper will take longer to sample, while in the case of offline sampling, a long paper will take longer to sample. Because the length of the paper is different, the sampling results will come out at different times.

Finally, the way of paper sampling will also affect the time-consuming of repeated sampling. Generally speaking, it takes less time to adopt automatic sampling, while it takes longer time to adopt manual sampling.

Generally speaking, the school will adopt a comprehensive sampling method, that is, the combination of automatic sampling and manual sampling, which can ensure the accuracy and reliability of sampling, but it also means that the sampling time will be longer.

In a word, the time-consuming of duplicate sampling for undergraduate graduation thesis can generally produce the results within 24-48 hours after submission, but the actual time-consuming will also be different due to many factors such as the school, the number of words in the thesis, the sampling method of the thesis and so on.

Therefore, when submitting graduation thesis, students should understand the sampling method of the school and shorten the sampling time as much as possible, so as to successfully complete the duplicate checking and sampling of graduation thesis.
