In Order of the Phoenix, Harry, Luna, Ginny, and others all do magic at the Ministry of Magic, which is definitely not on school grounds. 23skidoo 14:26, February 25, 2010 (UTC)

presence of muggles

I don't understand why Dudley counted as him and his family have already been informed that Harry is a wizard, you would think that in the case of muggle borns or half bloods with a muggle parent, that those muggles wouldn't count in this law. --BachLynnGryffindorcrest(Accio!) 00:13, October 7, 2010 (UTC)

underage magic and home-schooling

It is known that Hogwarts attendance is not mandatory, except in 1997 - 98. Is there any canon evidence how home-schooled wizards learn to cast spells. Is their education purely theoretical or is an exception made for them? It may be worth mentioning in the BTS SECTION:--Rodolphus (talk) 18:14, July 25, 2015 (UTC)
