The Departments of Mathematics and Computer Science have collaboratively mapped out a data science pathway for an IDM (interdepartmental major) between the two departments. This pathway makes it easier for you to identify courses relevant to a career in data science, and to plan and optimize your program of study accordingly.

Note that this IDM is intended for students interested in data science and its mathematical foundations, but not necessarily all the lower-level computational aspects. Depending on your interests, the other options include:

- The
**Data Science Concentration**within the COMPSCI major, which requires fewer courses on the mathematical and statistical foundations, but focuses more on the computational aspect and practical issues that arise in applying data science. - The IDM in
**STA+CS on Data Science**, which covers more topics on statistical data analysis.

### Prerequisites:

- CompSci 101L or 102 or 116 or equivalent
- Math 111L and 112L or equivalent
- Math 212 or 222 (but not 202)

These courses/credits will not count towards the 14 required courses below.

### From Computer Science:
