Hermione had never struggled with handling her workload — not really, anyway, not when it counted. In her third year, she used a Time-Turner to get to her classes. In her fifth, she prepared for O.W.L.s months early. During her internship, she managed not only her own calendar, but also those of  two  of her superiors. She was easily the most organized person in the entire department, and possibly in the entire Ministry.
