It is difficult to imagine a broader choice of majors than that offered by Berkeley’s College of Letter and Science. Here you may pick from among 70 majors across the arts and humanities, biological sciences, mathematical and physical sciences, and social sciences — or else you may opt for an interdisciplinary major. You must declare a major before the first semester of your junior year. To begin to explore the possibilities, consult the list of majors, browse through the General Catalog, contact someone in a department of interest to you, and always take advantage of the assistance provided by advisors in the L&S Office of Undergraduate Advising. If you are sure of your choice, it is to your advantage to declare a major early, in order to receive a higher priority for enrolling in courses in your department. If you’re still exploring possibilities, take introductory courses related to majors you are considering and avail yourself of every opportunity to explore as many fields of knowledge as possible.
