When Asking For An Extension At School messages in a Friendly tone

I’m running behind on this and wanted to check if an extension is an option.

I underestimated how long this would take and want to do it right.

I’d be able to submit it by tomorrow if that’s acceptable.

I appreciate your time and understanding.

Just an extra day would make a big difference.
