Sophie watched as the spell dummies materialized before her eyes. There were only four of them, which meant the professor didn't have much hope that they'd succeed. If she did, she'd have at least one for every person here. Sophie was nowhere near non-verbal status when it came to spells, so she'd be practicing it out loud.

She positioned herself in front of the first dummy and raised her wand. "Carpe Retractum!" she called out, making a tight, whip-like motion toward the dummy. A purple rope sprung from her wand but only went a foot forward before it fizzled out into pure nothingness. Meh. Why did this always happen? It could never be on the first try alone, could it?
