# B.S. Electives & Pathways

Within the B.S. in Data Science, students expand their expertise by taking three higher-level courses (>100) from the offerings in Statistics, CS, Mathematics, or the following pre-approved list. Each course must be at least 3 units, and the courses should be selected from the offerings of at least two different departments.

With advisor approval, courses other than those listed or offered by the sponsoring departments may be used to fulfill part of the elective requirement. Courses must provide skills relevant to the Data Science degree and not overlap courses in the student's program. Depending on a student’s interests, these courses may be in fields such as biology, economics, electrical engineering, industrial engineering, or medicine. To initiate this process, please fill out the Elective Approval Form and have a conversation with your program advisor.

Examples of courses that would NOT count as electives because of significant overlap with other required major courses or content too far removed from Data Science are ECON 102A, ENGR 108, MS&E 120, and MS&E 140.

Students can use research units from a 199 course for a maximum of three units toward the Data Science electives if the research is related to data science and approved by their advisor and the program.

##
Individualized Concentration Option

Some students may choose to pursue an individualized concentration in place of their electives. The Data Science program has designed three such paths for students who want to pursue their interests in fields where applied mathematics and statistical analysis is utilized. Declared Data Science B.S. majors are not required to choose a path.

##
Biology Path

The biology path is intended for students interested in pursuing a graduate degree in the bioinformatics and biostatistics related fields who declared before September 1, 2023 (when the official Biology and Medicine subplan was created).

Take three courses from the Biology core:

- BIO 82
- BIO 83
- BIO 84
- BIO 85
- BIO 86

OR Take **two classes from the above** biology core and take **one **of the following:

- BIO 104
- BIO 118
- BIO 133
- BIO 144
- BIO 183
- BIO 187
- BIO 230

Other Notes:

- Honors students should take BIO 113, BIO 114, and STATS 155.
- Bio/Stats 141 can replace STATS 191 (Introduction to Applied Statistics) or STATS 203 (Introduction to Regression Models and Analysis of Variance).

##
Engineering Path

Take one course from the following:

- Math 106
- Math 108
- Math 116
