I think Hermione from Harry Potter and the Order of the Phinox is a determind 5th year girl and is very strict about Harry and Ron finishing their homework before it is due.She is very worried about the O.W.L.S exams they have to take later on in the year,and after the exams Hermione looking over the exams paper to make sure she got every answer rhigt .After the exams Hermione is very exited for next years exams while she is sitting under the beach tree on the Hogwarts grounds.
