# B.S. Degree Requirements 2023-2024

These updated degree requirements apply to students who declare on or after September 1, 2023.

Following careful review by the Data Science team, there are two changes from the previous year's requirements:

- DATASCI 112 has been added as a gateway course.
- Two official subplans have been created, and students will be required to choose one:
- Mathematics and Computation subplan
- This option will allow students to follow the same requirements as those in the previous academic year (with the addition of DATASCI 112 as a gateway course). Some requirements have simply been rearranged to fit into the structure of the subplan.
- This subplan is largely in response to feedback from students that the words Mathematics and Computation are important in reflecting the content of the major. Thus, the subplan will allow this language to be included in the name of the degree.

- Biology and Medicine subplan
- This option is intended for students with a particular interest in biological processes and the analysis of health and biological data. This subplan includes a set of biology classes that is recommended for students interested in applying to medical school.

##
Capstone Experience (1 unit or more)

Data Science B.S. majors will have the opportunity to integrate the knowledge and skills acquired during their studies and think independently and creatively using the tools of the discipline during a capstone experience, which is an essential part of the undergraduate program. There are a variety of ways to complete the Capstone requirement, both within and outside Data Science.

To satisfy the capstone requirement, choose one of the following options:

- The Data Science Experience (DATASCI 190, 1 unit). This course satisfies the Capstone Requirement if taken after or concurrently with Data Narratives (DATASCI 120, 3 units). DATASCI 120 can be double-counted for the WIM and part of this capstone option.
- Data Science Practicum I (DATASCI 192A, 2 units) & Data Science Practicum II (DATASCI 192B, 2 units)
- Data Science Honors Program
- Notation in Science Communication
- Completing a project-based class in another department that involves significant data science work could also be considered for the capstone requirement. The class would need to be pre-approved by the program. Examples from the past include BIODS 217 and HISTORY 238C.
- Completing an independent research project in Data Science with a final portfolio could also be considered for the capstone requirement. This project would need to be pre-approved by the program.
