Hermione was full of rage during her Transfiguration lesson. She was finding it difficult to turn her arm into a wing of an eagle. Professor McGonagall had the advanced students of Transfiguration work on human transfiguration, but Hermione’s mind was in another land and she was unable to complete her task for the lesson. Hermione doubted she would have been able to do it even with her mind on the lesson, because this was just introductory practice; Professor McGonagall had them all test it out before getting into the advanced part of it. Unsurprisingly, the entire class was failing and it wasn’t until another ten minutes of trying and failing that Professor McGonagall had them all stop.
