For the Hogwarts thing you must join at least the seven main core classes (Transfiguration, Potions, Charms, History of Magic, Herbology, Astronomy, and Defense Against the Dark Arts). Electives are extra :) I need professors for these classes so if you want to be one fill the bio and do research on the class and teach it here's the studio make sure to check and the projects if you haven't already: https://scratch.mit.edu/studios/28154120/projects/
