After the Defence Against the Dark Arts classroom, which restored my years 1-4 spells, the ghost coins led me to a blue arrow pointing in front of a blank wall, with a lion's head above it.
I am guessing I need to open it, but pulling the torches doesn't do the trick? How do I get the wall to open?

To the left of the wall there is a student with a ladle looking object above his head.
Go down the stairs and look for a student carrying the ladle. Zap him 3-4 times with your attack spell and he will drop it. Bring the item back to the first student and the wall will explode.
