Although you have written the whole paper by yourself, the repeated use of some sentences will also lead to a decline in your subordination rate. As long as a lot of places are changed, it may be too late to correct the weight one day in advance. You must leave enough time for subsequent corrections to make up for the shortcomings. When I added my graduation thesis, it was not enough to check my weight three days in advance. Many places are marked red, and my paper has been revised for three days and three nights.
It is best to write your graduation thesis by yourself, and complete it according to your own personal experience and all the knowledge you have learned. Don't think about opportunism, just copy a long paragraph of text online. In this way, you will be even worse. If you take screenshots online for a long time, when I help you check the duplicate, basically the whole article will fail. When the teacher finds out that your paper is copied online, it will be troublesome, which will not only affect your graduation, but also may question you as a whole.
Therefore, we must pay more attention to this aspect. We must do our best. There are many softwares that can search articles, but not everyone can reach the pass rate of 100%. Therefore, we must be psychologically prepared when checking the papers.
