Harry Potter and the Wizarding University

AU. Children do not receive letters inviting them to study magic at age 11. At age 18, on the other hand, they may be offered admission to Hogwarts University. After spending 17 years growing up at Number Four, Privet Drive, Harry Potter is visited by an individual of unusual size to be informed of his admission. Harry x Ginny... sort of. Violence and graphic content aplenty.
