There are not the specified number of duplicate checks. If 1 passes, there is no need to check the duplicate in the future. You should go to the website designated by the school to check the duplicate. Generally, it is HowNet, which is more authoritative and reliable. It also depends on the repetition rate stipulated by the school. Some schools stipulate that it is 30%, and it is ok not to exceed 30%. Of course, some tutors or colleges have higher requirements and will raise the standards on the basis of the proportion stipulated by the school, which needs to be measured according to the actual situation.

If it exceeds 30%, it is necessary to reduce the repetition rate according to the query report. There will be a red font on the duplicate check report. You can modify the red font to lighten the weight.

Schools generally provide two opportunities to check the copies of knowledge networks. I suggest you use other websites or find someone to check before using the school account. It's not very reliable, but I know it very well.

Write a good graduation thesis. First of all, we must choose a good topic.

The scope can't be too big, we should start small. The theoretical foundation should be solid and a large amount of data should be collected. The research process should be fully reasonable and the conclusion should be concise and to the point. It is also necessary to communicate with the tutor in a timely and effective manner.

I hope my answer is helpful to you.
