This reminds me of some exams I did a while back. I was timed and it was not all an easy exam. The calculations were tough and I had limited time to answer. So as I kept thinking and calculating without a calculator, I was also keeping track of the time. You know at this point that every minute count, this is when you have to value the time you have.
I was able to finish at the last minute, but there were others who could not finish on time. Some folks needed just a minute to tidy up their work, they now know the essence of a minute.
One minute left is like a reminder that you have limited time left, it is wise to make good use of it.
