Ghoul Studies is a class taught at Hogwarts School of Witchcraft and Wizardry. Despite it being a class in its own right, it is not a core nor elective subject, so it must be extra-curricular or optional. The subject presumably focuses on ghouls, ghosts, and poltergeists. This class is taught in a classroom on the Serpentine Corridor, located in the Hogwarts Turris Magnus. It is unknown who teaches this subject.
