The work of a teacher can be very tiring and sometimes outrightly frustrating especially when students decide to pull their pranks during exams.
So, you are an invigilator and walked into the exam hall only to meet the students sitting like the ones in the picture above; One is looking at his phone and copying answers from it, the second is staring at the student with the phone to copy his answers while third simply tries to steal from the second student.
What will you do about it? Who will you punish?
