Declaring a Major
Students in L&S are expected to declare a major before the first semester of their junior year (for transfer students, before the beginning of the second semester at Berkeley). Those who do not declare by that time will be subject to a registration block, so it is imperative to declare on time. There are other good reasons to declare as soon as you are ready. As a declared student, you will be given higher priority to enroll in courses in your major department, and you will have greater access to departmental advising and other departmental resources.
To declare, print a copy of the Petition to Declare a Major and have it signed by the undergraduate major adviser (UMA) for your chosen major. At your meeting with the UMA, it is helpful (and for some majors, required) to bring an updated copy of your Berkeley transcript with you and copies of transcripts for courses taken at other institutions.
