You copied the homework and got caught. Grace doesn’t cancel the zero. It cancels the idea that you’re beyond change.

Two things can be true: the consequence stands and you are not finished. A zero is a fact about one assignment, and it is supposed to sting. What it is not is a description of your character going forward. People confuse the two and then either fight the consequence or accept the verdict, when the honest move is to take the first and refuse the second.

Take the penalty without negotiating it down, which is the fastest way to be done. Then work out what you will do next time the deadline looks impossible. Ask for the extension, badly and early, instead of copying.
