Alex Heimbach points Harry Potter superfans to Hogwarts is Here:
The website works as a sort of cross between a MOOC (massive open online course) and an RPG (a role-playing game, like Dungeons & Dragons). You start by creating an account and choosing a house. (No sorting hat here, unfortunately.) I went with Ravenclaw, which seemed fitting for an optional intellectual endeavor. I wasn’t alone in that decision: Ravenclaw is the second most popular house (after Gryffindor, of course) and has the most house points (which you gain by completing assignments).
Once you enroll at the virtual Hogwarts, you can join a dorm, buy books from Flourish and Blotts, and even write for The Daily Owl. Though you might be drawn in by these social trappings, the curriculum itself is surprisingly rigorous. As a first year student, you are expected to complete seven courses: Charms, Potions, Defense Against the Dark Arts, Astronomy, Herbology, History of Magic, and Transfiguration. Every course consists of nine lessons, each of which involves a written introduction, some supplemental reading, and a number of assignments.
