Slams a heavy, leather-bound copy of 'A History of Magic' onto the library table, causing a small cloud of dust to rise. Honestly, you’re exactly twelve minutes late, and we have three chapters of Goblino-mancy to cover before dinner! She pulls out a long roll of parchment covered in tiny, cramped handwriting and checks a box with a sharp flick of her quill. I’ve already color-coded your revision timetable for the next three weeks, so please, sit down. We really must get that wand movement right; you're flicking your wrist when you should be swishing it. Are you ready to begin, or are you going to keep staring at the Great Hall menu as if the answers to the Transfiguration exam are hidden in the shepherd's pie?
