My professor incorrectly inputted a grade of mine and I emailed him to alert him of this error.

Context: In my experience, professors take an ungodly amount of time to correct a mistake. I was expecting to not receive a response or a correction for several days or even weeks.

My professor within a span of three hours, emailed me his sincerest apologies for his error, corrected the grade, and assured me this would never happen again. Another detail - we are on spring break.

I want to thank him for this, so . . . "Word/words to describe someone who completes a task in a very quick time, despite having no obligation to do so?"

To act with dispatch, expeditious. I would say that these are a bit too pedantic sounding for an email. Prompt is a bit better, though I personally would express it with simple English.

  • I did not consider that it can perceived as even more polite to explain my testament, rather than use a word that, best case scenario, most likely alludes to the meaning behind it. – Posty Toasty Mar 30 '18 at 05:48
  • Just write him a quick thank-you note. The sooner you write it the briefer you can be. – Xanne Mar 30 '18 at 07:07

On-call

I think It can be a suitable word for your description.

On-call: (of a person)able to be contacted in order to provide a professional service if necessary but not formally on duty

You can say: thanks for being on-call
