A. An extra-curricular activity is any activity that you can participate outside of your class. It can be related to your school, such as a sports team or club, or completely separate. Extra-curriculars can include a great range of activities or interests, from painting to debates to helping the homeless or more. Extra-curriculars are a necessary part of your college application. The colleges wish to understand what type of an individual you are and what type of leadership qualities you portray. So, mention the extra-curricular activities in such a way that highlights your ambitious personality and determination.
