Today we had our final exams for the course. There were 550 students, all taking their exams in a giant multi-purpose sports hall. Students were assigned a desk by number and roster and the some TAs and the lecturing staff were walking around during the exam to answer questions, etc. It was quite something. I haven't had a class of that size before, so it was quite an experience. Furthermore because of SARS, all of the students were screened by volunteer medical students for sickness and high fever before they were allowed to take the exam.
