I seriously think that the merchants just take advantage of the students' psychology, because the requirements for duplicate checking are getting stricter and stricter now. If the duplicate check fails and the degree certificate is not obtained directly, the students will be very nervous. Will there be problems with their tea pets? Although many people write their own graduation thesis, it is impossible for an undergraduate to write some theoretical parts, so we must learn from them. Will this duplicate checking rate exceed the requirements of the school?
Therefore, students' worries are not unreasonable, because everyone's topics are different, and some topics are written by many people, so the duplicate checking rate is relatively high. Coupled with the theoretical part of the paper, it is possible that the duplicate checking rate will be a little higher, so many people will choose to buy a duplicate checking service before finalizing it, but these businesses are really crazy about money and adjust the price so high.
I think another point is that some schools don't give students free time to check the duplicate. In our school, you hand it in, and if you fail, you argue, and the students are under great pressure. Even if I know I wrote it myself, I'm not sure I can pass a duplicate check, but I asked many students, and they all gave away the duplicate check times for free, ranging from one to three times. I think it is also possible.
