In one of the books, I think it was OoTP, one of the people trying out for the Gryffindor Quidditch team mentioned that if practice clashed with Charms Club she would go to Charms Club.
This got me thinking a bit about extra-curricular clubs at Hogwarts. What do you think students do in Charms Club? Do they learn new Charms, more advanced Charms? Do they try to invent their own? Do you think the students that were in Charms Club would be ultra-competitive in lessons? Would they have a reputation of being swots? Would Professor Flitwick preside over Charms Club or would there be an elected student leader?
I'm interested in what other people think because in my high school we didn't have extra-curricular subject based clubs like this. Any ideas would be much appreciated!!
