You'll notice when you receive your room allocation in a few minutes that your room number either begins with the letter N,S,or W like this one here.The first letter refers to the three wings of the college which come away from this main building.Of course the letters represent the three directions - in this case - north,south and west.Each wing has two floors,and so the next number you see is either one,or in this case tow,and this indicates which floor your room is on.The number after that is your individual room number.So it's quite simple to find any room by going to the right wing,then floor,and then room number.
