After the paper is sent to the teacher, the teacher will comment on your paper, which you can't upload.

Reorganize a paper according to the suggestion. Just submit it

I don't want to delete it. I suggest you make a copy, send one to the teacher for revision, and keep the other for yourself. In this case, you watch the teacher's comments change, and your own copy still has no comments.

I don't know the answer, can you make it clear?
