Registration at Western University has always been a time of emotion, commotion and lines. Students must move among four stations to complete the trying semi-annual process. Last semesters registration, held in the field house is described in the table below. You can see, for example, that 450 students moved from the paperwork station A to advising station (B) and 550 went directly from A to picking up their class cards (C). Graduate students, who for the most part had pre-registered, proceeded directly from A to the station where registration is verified and payment collected (D). The layout used last semester is shown in the diagram below. The distance between successive stations is 30 feet each. The Registrar is preparing to set up this years plan and is anticipating similar number of students.
