Generally speaking, there is only one chance to check the graduation thesis. If repeated inspection fails, there are generally two situations:

The school has the opportunity to check the weight for free. If the first duplicate check fails, you can apply to the school for a free duplicate check again and submit your paper again for duplicate check.

If the school does not provide free duplicate checking opportunities, or has used up free opportunities, you need to find duplicate checking software to check duplicates yourself.

If the paper still fails to pass the duplicate check, it may need to be revised or rewritten according to the requirements of the school. If you fail to pass the re-examination, it may affect the graduation process.
