I had been in my new school for only four weeks when this happened to me. It was a Monday and we were supposed to have a math’s test.
When I entered my class I saw a room full of new faces. I thought the few classmates I knew might have bunked the test, I went and sat on the last bench.
Then a history teacher came in and started teaching. I was so happy that there was no math’s test. I started relaxing on the last bench.
It was only after the period was over and I saw a classmate coming out of an adjoining class carrying a math’s test paper that I realized I had been sitting in the wrong classroom.
