All what are examples of extracurricular activities except what?

Extracurricular activities are things done outside of regular school classes. Therefore, examples of things that are *not* extracurricular activities would include:

* Classes/Subjects: Math, Science, English, History, etc. These are part of the regular curriculum.

* Homework: Assignments given as part of regular coursework.

* Tests/Exams: Assessments of classroom learning.

* Required School Events: Things like mandatory assemblies or fire drills. While they take place at school, they aren't chosen by the student.

Essentially, anything that's a required part of the formal school day or directly related to completing academic requirements is *not* an extracurricular activity.
