Q: Where is MSB room XXXX?

Yes, the room numbering system in the MSB is confusing! Look at the 4-digit number of the room in question. The first digit is the floor number, the basement being the first floor. The second digit represents north/south, starting with 1 for the north end of the building (towards King’s College Circle) to 3 for the south end (towards College Street). The third and fourth digits represent east/west, starting with 01 for the east end of the building (towards Queens Park) to 99 for the west end (towards Convocation Hall).
