UC San Diego undergraduate students who would like to change from another major or undeclared to the Business Data Science major should apply via the Selective Major Application. Applications must be submitted on or before the deadline September 1, 2026. Fall 2026 applicants only, will select the Data Science major (DSC-BS-001) on the application. 

Applicants admitted to this selective major will be contacted in Fall 2026 and given the opportunity to choose between the Data Science major (DSC-BS-001) and the new Business Data Science major (DSC-BS-002 - code pending) in the Fall. 

Students may find more information and apply for the major on the Selective Major Guidance webpage. 

The Business Data Science major can be combined with any major or minor, except for the Business minor (RSM-MN-002), the Data Science minor (DSC-MN-001), and the Data Science major (DSC-BS-001). 

Important Notes for Fall 2026 Applicants: 

• If you apply, you should plan your Fall 2026 courses as if you have been accepted into the major.
• Double Majors- Due to challenges related to the transition to the new Triton Student System, double major petitions will not be accepted until the end of Fall quarter. 

In addition to the eligibility criteria outlined on the Selective Major Guidance page, Business Data Science requires successful completion of the following 3 screening courses: (MATH 18 or MATH 31AH), (MATH 20C or MATH 31BH), and DSC 10.

Courses must be completed for a letter grade at the time of the Selective Major Application to be eligible. Students may not have any outstanding grades for screening courses or any reason (e.g., Incompletes, pending Academic Integrity case, etc.). Grades from transfer credit for screening courses will be used to determine eligibility.

Students who entered UC San Diego as first-years: 

Students must be on track to complete DSC-030 and DSC-040A prior to their third academic year at UC San Diego to be on a 4-year graduation track.

Students who entered UC San Diego as transfers:
