Enrollment for Fall 2025
Updated Apr 13, 2025
Regarding requirements
The current Brown Bulletin URL goes to the 25-26 Bulletin, meaning that the listed requirements take effect in Fall 2025. If you declare in Spring 2025, your requirements follow the 24-25 Bulletin. For CS requirements, in particular, the 24-25 Bulletin lists more courses as satisfying the foundations courses. Also, APMA has made significant changes to their requirements starting in Fall 2025. ASK forms will update to the 2025 bulletin during summer 2025.
You may find the CS-maintained requirements pages easier to navigate, as we have tried to summarize multiple years on one page.
- CS concentrations for Fall 2024 and Fall 2025 (the so-called "new" requirements, classes of 2028 and some 2027)
- CS concentrations from 2020 (the "old" requirements, class of 2026 and some 2027)
- APMA-CS (Fall 2024 and 2025, see the pages for links to the earlier requirements)
- CS-ECON (Fall 2024 and 2025, see the pages for links to the earlier requirements)
- MATH-CS (Fall 2024 and 2025, see the pages for links to the earlier requirements)
Notes on Prerequisite Changes taking affect in Fall 2025-Spring 2026
CS 500 and CS 1570 are getting stricter about math prerequisites. Both courses will assume that you have experience with proofs, such as through CS 220 or MATH 540 (but NOT MATH 520 or APMA 0260). Starting in Fall 2026, CS 500 will be a prereq for undergrads to take CS 1570.
For undergrads, the 1000-level AI courses will start requiring CSCI 0410 or 1411 in Fall 25/Spring 26. Rising seniors/juniors (current juniors/sophomores) will be able to use existing 1000-level AI courses as a replacement (through overrides this fall). If you have not yet taken 1000-level AI courses (this semester or earlier), you will need to take CSCI 410 first.
Graduate students will be able to register for 1570 and 1000-level AI courses through the standard prereq WAIVE, but you should be aware that the 1000-level AI courses will start assuming that you have already had an introduction to AI.

Frequently Asked Questions
-
I didn't get a seat before the cap was reached. What do I do?
Every semester, there is a lot of turnover in who enrolls throughout shopping period. Seats are likely to open up in most courses as shopping period plays out. Keep an eye out during pre-registration, and try for a seat again when the semester starts if you still need one at that time. Some faculty maintain their own waitlists: see the CAB entry to find out of this applies to you.
- I didn't get into a course that I needed to graduate. What do I do?
Reach out to your academic advisor to figure out alternate arrangements. If your advisor isn't sure what to do, reach out to the Director of Undergrad Studies (Kathi Fisler) or the Director of Masters Studies (Nikos Triandopoulos).
- I requested an override but haven't heard anything. What do I do?
Each instructor decides how to handle overrides for their own courses. Many faculty will not issue any overrides until shopping period begins.
