6 Hours of Invigilation

For the first time, I went for invigilation for 6 hours... Usually I just went for release only... For about 15 to 20 minutes... But this time onwards, I will be invigilating~ Nice experience... Since I was a student not long ago, I at least know students' behavior during exam... But luckily no copy case... If not, I really don't know how to handle them... I guess I will be calling exam department and ask for help... Haha...
