Daniel Radcliffe and Emma Watson in 'Deathly Hallows, Pt. 1'

These days, you don't have to be a wizard to have Harry Potter in your classroom. In colleges and universities across the U.S., Potter-themed courses are regularly offered -- and no, we're not talking about Defense Against the Dark Arts 101 or Care of Magical Creatures Lab (too bad!) -- but classes based on J.K. Rowling's book series and the movies they spawned.

In fact, so many institutions of higher learning have used Potter in their curricula, it's hard to keep track at this point. These courses are offered not just by English departments, but in medieval studies, theology and physics, among other fields.

While many schools use Harry as a way to introduce students to subjects they might otherwise not pursue, these are not necessarily easy-A classes. By and large, they are, however, extremely popular, with fierce competition for limited seats. Naturally, the professors who originate the classes tend to be imaginative types, not unlike certain Hogwarts instructors. (And yes, at least one has worn wizard robes while teaching.)

In anticipation of 'Harry Potter and the Deathly Hallows, Pt. 1,' opening next Friday, Moviefone has tracked down a sampling of recently taught Potter-related courses.
