I cannot explain what I did today. I had an exam which I was appearing today. Today, I went to appear the exam and then I found out that the exam for which I prepared for was not today, rather it was 2 days later.
I could not think what to do, so I went to the library and wrote some notes which was very helpful during the exam. I could not believe how foolish I was to make such a silly mistake, never happened to me before.
