You will find your class location on your class schedule and immediately
assume that you have entered the Twilight Zone; however, it actually does make sense. Classrooms on campus are designated by a number followed by a letter or group of letters. The first digit of the number represents the floor of a building in which a class is located, while the letter or letters designate the actual building. For example, Room 1304-S (south) is on the thirteenth floor of the 624 South Michigan Avenue building - abbreviations are listed below:
