Electives are what you choose to take. Your degree program or specialization may provide you with the opportunity to take free electives (i.e. any course in any subject area), require you to take electives in a specific discipline (i.e. Arts or Social Science electives) or provide a list of elective courses to choose from (i.e. restricted electives). If you think you may pursue graduate studies (i.e. a M.Sc. program) or a professional program (i.e. medical school) in the future you may wish to take electives that will also satisfy entrance requirements for these programs.
