People think writing examination is difficult. But they don't see the difficulties of the invigilator. If you see any organised exam hall, you see a poor man moving over and over again on the same path between the rows of benches with a definite frequency. He is hero to himself and villian to the candidates.
He should not sit, read, take a nap, touch the mobile phone, moreover the lecturer should not lecture/talk during the three hours period. I am afraid if the invigilator is also prohibited to think in his mind about anything.
Only one interesting thing is that cup of tea. He should be as alert as a vip security gunman. He should invent and practice innovative methods to curb malpractice. If he finds any two of the examinees murmuring, he should immediately roar like a lion so that those two candidates fear to talk with each other for life time i mean outside the exam hall also. He should stand at the back of the examinees. If he notices any one repeatedly turning backwards, he confirms he has a chit and he is trying to copy. He must at once jump to the spot and investigate his belongings like writing pad, take away the chits, create a big scene, his mission is successful.
