This message was left on a whiteboard in an SIM revision room, warning students not to get intimate with their partners in the room, among other things. STOMPer DS , who saw the photo online, said: "This photo was taken by an SIM (Singapore Institute of Management) student in one of the revision rooms. "As an SIM student, this is also what I experience in the revision rooms. It is not an isolated case. "The revision rooms in SIM have become a playground. "People talk and talk, disregarding other students who are serious about studying. "Some even brought their guitar into the rooms to play. "Totally unbecoming of students. I wonder why undergrads in SIM are so inconsiderate."
