Look through your college's course catalog, usually available at the registrar's office or online. Learn what courses are offered outside of your major. Consider your non-academic interests, such as art or music, or a skill you always wanted to learn, such as speaking a foreign language or sign language, and look for courses in those areas.
Learn what your major requires for graduation, including the total number of credits, the number of credits that must be major-specific, core or general education courses and internships. Look for information provided on electives to learn how many non-major courses you can reasonably fit into your schedule while meeting the graduation requirements.
Prioritize the electives you are interested in based on availability in your schedule and how often the courses are offered. Consider taking elective courses that are offered only occasionally sooner rather than later, so you do not miss the opportunity. Make a rough time line of when you would like to take the other elective courses during your college career.
Meet with your academic adviser to talk about your electives options. Ask for advice on fitting in the classes and spacing them out over your academic career. Show the adviser your time line and get feedback on your plan.
Complete all necessary paperwork and permission forms to register. Some colleges require permission from the instructor, dean or academic adviser to take courses outside of your major. Ask if you can complete this paperwork before the registration period to lessen the chance that the class will fill up.
Continue to monitor the course catalog throughout your college years and revise your electives time line to reflect your interests and the availability in your schedule.
