Undergrad Electives

Upper Division Electives List Explained:

UP TO TWO Upper Division courses from other departments may be taken as electives by IB majors, toward the minimum upper division requirements of 24 units (toward 26 unit upper div minimum for those using "Old" IB Curriculum). Electives are still subjected to overlap restrictions: one upper-division course total between IB and a minor, two upper-division courses total between IB and another major.

  • The courses listed below have been approved by the IB faculty, and may be taken as electives without further approval from an IB Faculty Advisor.
  • Students interested in other courses for use as IB Electives shall first bring a course syllabus to the IB Undergraduate Student Services Office, and can then seek approval from a Faculty Advisor.
  • This list of pre-approved electives will be expanded over time as the IB Faculty are able to review additional syllabi for courses of interest to our undergraduates.
  • The approval of these courses indicates that they offer content relevant for IB majors, but does not constitute a specific recommendation.
  • Students are responsible for determining that they have adequate prerequisites and background when enrolling in courses in other departments. If used for the major as an elective, such courses MUST be completed on a letter-graded basis.
  • The courses on this list may NOT be taken to satisfy Requirement Groups A, B, or C, or the IB lab requirement.
