Well, the building you to go is Gilmour Hall.
that's right beside the Student Centre!
and after you walk up the steps and get into the door, you should see the "Financial Aid and Scholarship" room, so when you see that, TURN LEFT.
then walk walk walk
and then go RIGHT, and you will see the Office of the Registrar.
I can't remember the room number, I just know how to get there, lol.
