Tell me about a time when you made a mistake how did you find it and what did you do to correct it

Once what happened was that the test paper was of Social Studies and i have studied maths. This all happened because i read the old time table. Now what could i have done? Only 1 hour was left for the paper with my classmates laughing at me. Well that laugh didnt matter at all at them moment because the important part was the Test and i wasnt that good in the subject now what? I thought of ways for 5 minutes like acting for a stomach ache but it wouldnt work i would have to give the test in the infirmary! I was devastated but only i could do was to study, i sat on my seat quickly took my books out with the help of a few friends and with there notes i was able to study the whole chapter and give my test happily my marks were not that good. But i learned my lesson to keep my time table updated atleast.

Note: Not a true story i just wrote whatever came in my mind.
