I have got a chance to invigilate annual examinations for high school. The most boring job in the world is invigilation. It’s a big pain in the knees, neck and eyes- we need to stand and roam around the exam hall continuously for 2 and a half hours; keep eye on every student and turn both directions frequently. I have been seeing this stereotypical practice since my childhood.
Its physical science exam, pupils are literally bewildered at questions given in the paper.
Absolute silence in the school can be seen only during exams!
Discussing the questions with their peers, in front of a hawk eye invigilator!
