There is nothing to hide in front of the teacher. Honestly, why is it late? After all, this is only the first draft. Don't be smart, and don't find any reason to fill the position. You can't hide all this from the teacher. The key is that you should do the following work well. First of all, apologize to the teacher. If he hands it in late, he is a mistake. This must be deeply recognized. Second, I promise I will be more serious in the future and will not delay.
