I'll accept the British spelling now. I accept "Muggles" because that's the only class about them. History of magic has to be typed in because if I make just "magic" acceptable that's basically every class in the school.
There's so much on the Harry Potter Wiki. Apparently he took a year-long sabbatical to get "first-hand" experience on muggles, but was actually searching for whatever was left of Voldemort. They also have Professor McGonagall's signature. Apparently it was Professor Flitwick's birthday yesterday too! I didn't celebrate but I'm sure some diehard Potterhead did.
amycus taught DARK ARTS not DEFENCE AGAINST THE dark arts and there are two carrows but even if it's just one you should state whether it was amycus or alecto
Professor Grubbly-Plank taught Care of Magical Creatures, Professor Vector taught Arithmancy and Professor Babbling taught Ancient Runes, Could you add these please. :)
Also, why do you accept 'muggle' without the need for 'studies' having to follow it when you have to write out 'history of magic?'
