At least half of the AUC programme is dedicated to taking major courses, and another third to the Academic Core, but this means that there is still plenty of room in the programme for freely chosen courses: the electives.
You can use your electives to broaden and deepen your education in a variety of ways. You may prefer to try out a range of different subjects and pursue diverse interests, or you may choose to take your electives in a single subject area to fulfil the requirements of a ‘minor'. You can select your electives from a wide range of courses, including those offered outside of your major (as long as you fulfil any prerequisites), and courses in the Academic Core that may not necessarily be part of the requirements for your degree. There may also be some specially designed elective courses available and/or courses offered in collaboration with other institutions (such as UvA/VU honours courses or participating in a semester abroad).
Your future ambitions will also influence your choice of electives. Perhaps you will decide to use your electives to supplement your major and specialise even further in certain subjects to better prepare yourself for more specific degrees at the Master or PhD levels. Regardless of your situation, you can always consult your tutor to help you in making the best use of your electives to balance and combine your interests and ambitions.
