The purpose of a course union is to enhance the ability of students to discover, pursue, and share their passions in a particular academic field. A course union may restrict membership to students in their particular academic field, or they may be open to all students. All students within the specific academic field are automatic members of the relative course union. A few examples of course union activities are: socializing, tutoring programs or group study sessions, supplying specific course materials, and/or advocating for students in their academic field.
Differing from a club, course unions must have a constitution, bylaws, hold AGM's and annual elections to elect their executives who run the course union for the year.
