You should know that there is still a prescribed process for graduation, and the process includes the graduation thesis. Under normal circumstances, the graduation thesis should be submitted in accordance with the prescribed time. You know, colleges and universities will leave enough time for everyone to write their papers.
So just submit the paper according to the stipulated time.
If it is not submitted within the specified time, it will not be able to participate in the follow-up link normally, but different institutions have different requirements in this regard.
If it is not completed within the specified time, some institutions can still allow you to postpone the submission, but this situation is rare. After all, every link has a prescribed process, and you still need to submit your graduation thesis within the prescribed time.
Whether the graduation thesis can be revised if it fails to pass the examination depends on the specific situation.
