Ordinary Wizarding Levels were the exams taken during students' fifth year at school. Subjects that were examined in the O.W.L.s included core subjects such as Potions and Charms as well as specialist subjects such as Ancient Runes, Arithmancy and Divination. Results determined what subjects a student could go on to study at N.E.W.T. level as well as potential future employment. In order to pass students had to achieve an Outstanding (O), Exceeds Expectations (E) or Acceptable (A). A Poor (P), Dreadful (D), or Troll (T) were failing grades.
