There are a variety of classes taught at Hogwarts School of Witchcraft and Wizardry. These include both the core curriculum and the electives, available from third year forward. In the fifth year, students take the Ordinary Wizarding Level (O.W.L.) exams to determine whether they can achieve a score to continue to Nastily Exhausting Wizarding Test (N.E.W.T.) levels of the class in the upcoming year. Some classes, including the core classes, may be dropped in sixth year. Some students may apply for Time-Turners to take more classes than possible to fit in the timetables, but they may have a choice to drop courses if they become a burden, aside from the essential classes.
