Anyway, Ron it's waiting for you at the Entrance Hall. Don't keep him waiting. Descend the stairs. Halfway down you meet up with Headless Nick, who seems to be a little d it'sappointed. After he departs continue down and enter the Entrance Hall. Ron it's standing next to the front door, so head past him and step outside to Hogwarts Grounds. Once outside take the right side path to Flying Practice, where you will learn to fly your broom.
