Hermione was noted for being extremely intelligent and hard-working, quite responsible, perfectionistic and well put-together, coming out on top in most of her classes and continuously aiding Harry and Ron in their adventures. She was so studious that the school gave her a Time-Turner in her third year, a device that rewinds time so that she could take extra courses. Because of her efficiency, she often had time to do hobby work on the side, such as preparing a defence for Buckbeak to save him from execution. Such acts demonstrate Hermione's social conscience, tenacity, and compassion. Unlike most wizards who depended solely on their magical ability, Hermione readily relied on logic. Although this often helped her cleverly deduce information that many others missed, such as Remus Lupin's lycanthropy, Hermione's emphasis on logic also made her skeptical about accepting anything without proof, as opposed to Harry who would come to intuitive conclusions.
