Uh... it said in the fouth book he was around 17... but that was a mistake, 'coz he couldn't be 17 until after December... yeah... now I'm really confused... Prami found another mistake. IT also said that (in the 4th book), after the World Cup thingy, when the death mark and junk happened, that Hermione used her wand (for lumos, all of them did), and they didn't get in trouble, and Hemione wouldn't use her wand since it's illegal.
