Declaring the Major

Based on changes to L&S and campus policy, courses completed at UC Berkeley with a grade of Pass in Spring 2020 will count toward Data Science major and minor requirements, including prerequisites to declare the major. Please see the L&S Spring 2020 P/NP policy updates for more information.

Declaration Eligibility

  • The prerequisites to declare the L&S Data Science major are Foundations of Data Science, Calculus I, Calculus II, Linear Algebra, Program Structures, and Data Structures.

  • All prerequisites to declare must be completed for a letter grade and passed with a 'C-' or higher.

  • Students must achieve a 2.0 Grade Point Average in Data 8, Linear Algebra, and Data Structures to be eligible to declare. The grades earned in Calculus I & II and Program Structures will not be factored into this GPA requirement.

  • If a student chooses to take more than one upper-division course toward the major prior to declaring, they must have a minimum 2.0 Grade Point Average in all upper-division courses completed toward the major at the time of declaration.

  • The Data Science major follows UC Berkeley policy on repeating courses; you may repeat a course only if you received a grade of D+, D, D-, F, or no pass (NP), and if you have taken the course only once before. You must repeat the course for a letter grade. Both grades will show on your transcript, but only your most recent grade will be calculated into your GPA for declaration of the major.

Any student taking one or more declaration courses in Spring 2020 may declare the Data Science major at the end of Spring 2020 if they have completed all required courses to declare, received letter grades of C- or higher for the courses taken prior to Spring 2020, and receive grades of Pass or C- or higher for the courses taken in Spring 2020. The 2.0 GPA requirement to declare will be waived for students meeting these criteria in Spring 2020.

For example, a student who completed Data 8 with a C and Math 54 with a C- prior to Spring 2020, and completes CS 61B with a Pass in Spring 2020 will be eligible to declare the Data Science major at the end of Spring 2020.
