Beat the first level of the game
Complete the "Forbidden Forest" level.
Walk around an area with Bubotubers near a cauldron. Use Wingardium Leviosa on the Cauldron to lift it in the air, then guide the cauldron towards the Bubotuber. A successful strike will explode the cauldron and the Bubotuber and clear the way. If you cause the explosion near a creature they will take damage. The best place to try this at is Dragon Woods, near the dragon fly-by. This works best with one or more players.
On the first task you can hold down the R button to speed up.
On the first task hold down the R button once you start to fly thru the hogwarts exterior. When you get to that big wall harry will fly over it and in front of him will be 2 big towers with the dragon in the middle. The dragon will fly towards you and so you will have to fly towards him to make them collide and harry will fly straight thru him like a ghost.
