    • Courses must be completed for a letter grade at the time of the Selective Major Application to be eligible.

  3. Students who entered UC San Diego as Transfers must apply by their 3rd academic quarter.
  4. Students with 150+ units at the time of the application will need to submit a quarter-by-quarter (QxQ) plan for their remaining requirements to be reviewed by the DSC department and their college. QxQ plan must be emailed to no later than the Selective Major Application deadline.

Selection Process

  1. Students will be ranked based on their GPA in the 3 screening courses: (MATH 18 or MATH 31AH), (MATH 20C or MATH 31BH), and DSC 10.
    • Grades from transfer credit will be used in calculating the GPA for the screening courses, but not overall GPA.
  2. Students with the same GPA in the screening courses will be ranked by their overall GPA.
  3. Students will be admitted according to their ranking based on the number of available seats. If there are more students at a given rank than available seats, random selection will be made from among the students at that rank to fill in the remaining seats.

Time to Degree Considerations

Students who entered UC San Diego as First-Years: 

Students must be on track to complete DSC 30 and DSC 40A 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: 

Currently, the DSC major requires a minimum of 8 quarters for transfer students to complete. To remain on this 8-quarter transfer plan, transfer students must be on track to complete DSC 30 and DSC 40A prior to their second academic year at UC San Diego.
