Answer:
Dear [Professor/Instructor],
I am writing to apologize for failing to submit my project work on. I understand that this has caused inconvenience and I take full responsibility for my actions.
Unfortunately, I had some unforeseen personal issues that took up a lot of my time and energy, which made it difficult for me to complete the project on time. However, I realize that these are not excuses for my failure and that I should have done a better job of managing my time and prioritizing my responsibilities.
I assure you that I am committed to completing the project and submitting it as soon as possible. I understand that this may result in a deduction in my grade, and I accept any consequences that may arise.
Once again, please accept my sincerest apologies for any inconvenience caused by my failure to submit the project on time. I will work hard to prevent such situations from happening in the future.
Sincerely,
[Your Name]
