Dear sir,
I have noticed that I made a mistake in writing my assignment and I presented mr.abc assignment and I was supposed to submit my assignment on “Topic” on 22 January. I would like to know should I delete this assignment entry from portal or should I leave this now.
I say sorry on my mistake and I hope next time I will be careful.

Regards,
Abc

On 22nd January I mistakenly submitted the 'Topic' assignment of Mr ABC instead of my own. Should I delete it from the portal?

Please accept my apologies for this error and my assurance that I shall be more careful in future.

Kind regards
