Declaring The Major

Not all students declaring Data Science will need to complete prerequisites prior to declaration. Please use the "Eligibility to Declare by Semester of Admission" tabs above to determine if this information is relevant to you.

Prerequisites to Declare

Transfer courses from other institutions will apply, if listed as equivalent on assist.org or approved as equivalent by UC Berkeley faculty, and if completed with a letter grade of C- or better. 

Not all students declaring will do so through comprehensive review. Please use the "Eligibility to Declare by Semester of Admission" tabs above to determine if this information is relevant to you.

What factors will be considered in the comprehensive review process?

Criteria will include your academic performance as well as your motivation to pursue the Data Science major. We support the University of California policy on the value of diverse viewpoints, including academic and intellectual breadth. If you listed a different field as your primary interest when you applied to UC Berkeley, then you should explain why your interest has changed.

Keep in mind that in a holistic review process no single criterion is of primary importance, nor do you have to be exceptional in every dimension. We urge you not to take on multiple activities in the hope of strengthening your application. Just tell us your background and goals simply and honestly. We will be listening for your own unique voice.

What are the minimum classes required to take before applying to the Data Science major?

Before submitting your application to the Data Science major, you must have completed Data C8 (or Stat 20), and at least 1 additional course in calculus (Math 1A, 16A, 10A or 1B) or program structures (Data/CompSci C88C, CompSci 61A, or Engin 7). Approved transfer courses and/or exam credit may be counted, as outlined on the Data Science website.

Additionally, applicants should be on track to complete the lower-division classes by the end of their 5th semester (1st semester as a transfer).

What are the minimum grades to apply for the Data Science major?

There is no minimum grade or GPA required to apply to the Data Science major, and all interested students are encouraged to apply.

If you do not pass a class on the first attempt, you may repeat a class one time for credit toward your UC GPA.

If admitted to the Data Science major, all students must have a minimum C- or better in each course toward the major in order to declare and graduate, and must have a minimum 2.0 GPA overall in the major and in the upper-division courses in the major.

Review additional FAQs about the comprehensive review process.

The application for the Data Science major is usually open from the 4th week of each term through the week after Finals, including during the Summer.

Please submit your application no earlier than the last 3 weeks of the term in which you will complete your prerequisites.
