Taking 2% of graduates every year means that the number of graduates this year is about 10, because universities are admitted by colleges. In the case of a large number of students, about 400 students will be enough. If our paper is really written by ourselves, it won't have much influence. Although the repetition rate in the past is required to be lower than now, this is a standard problem in the past. We didn't write it ourselves. 1 year, if your defense is normal, the teacher's score is not low, basically no problem.
Now the requirement for repetition rate is getting lower and lower. My school should remember that it is below 25%, which is higher than before. But at that time, the instructor of this paper said that you should check the corresponding professional website, and your repetition rate should be below 15%, because more than 25% is plagiarism, and it will be very troublesome to pass it directly. This school paper repetition rate query system is different from the standards on related professional websites. Therefore, when you write, you should consciously avoid the accumulation of more technical terms, because these technical terms cannot be changed and can only be expressed in your own language, which may exceed 13 words in a row, even if it is plagiarism. This is a problem that you should pay attention to when writing.
There are many strange methods for later revision, such as translating Chinese into English and then translating English back. This is the simplest choice of 1 time. If the repetition rate is still high, then you can see which parts are red-hot technical terms, and then say them in your own words. Maybe sometimes the usage of this word is not what we usually use, such as using some uncommon words, which is completely acceptable.
