The results of the O.W.L. exams are very important in determining the futures of young wizards. Although Harry does remarkably well, his grades are nowhere near as high as Hermione’s. Rowling reminds her readers once again that Harry is imperfect, subject to the same stresses and failures as any student, and that in spite of his powers and reputation as the “Chosen One,” he still has to study and often comes up short academically. Harry does receive an Exceeds Expectations in Defense Against the Dark Arts, which is telling given Harry’s birthright and supposed destiny. Obviously, Harry has been predestined to destroy the Dark Arts, and his natural affinity for the practice will only help Harry when he finally faces Voldemort.
