"Molly, enough. Most of these classes are not even dark. I mean for example English, Math, the foreign languages, music, arts, physical education, science, muggle history and geography are not dark classes, but simple muggle classes. Then, there is the religion class. This class is teaching muggle and magical religions. Furthermore, magical theory. Molly, we had this class during our time in Hogwarts and wizarding study is only for a year and was suggested by Muriel."
