Remember, teachers are human beings and need respect. Whether you hand in the unfinished manuscript directly or delay it without saying hello, it will make the instructor's impression low.

So you might as well communicate with the teacher directly and find a positive reason, such as looking for some inaccurate information, looking it up and so on. , and then delay submission for a few days.

But it must not be delayed. You know, if the tutor doesn't sign, you won't even have a chance to reply, let alone a diploma.

Write quickly.
