Declaring Computer Science for AB'25 Students
Dear Prospective AB'25 COS Concentrators
Below please find all the information you will need to declare your AB COS concentration and select your fall 2023 classes. We encourage you to review all the information below and if you have any questions contact the COS Undergraduate Program Team members listed below.
**Join us for the AB'25 Open House - To Be Announced.**
What are the prerequisites for the AB concentrators?
All students concentrating in computer science must take three prerequisite computer science courses: COS 126, COS 217, and COS 226. AB candidates must also take MAT 202 or 204 or EGR 154. MAT 103 is the pre-requisite for MAT 202 and hence most students will need to take this course as well.
How do I know if Computer Science is a good fit?
- Welcome to the Computer Science Undergraduate Program
- Browse the Computer Science website, especially the Undergraduate pages.
- Why COS? Advice from the Computer Science Undergraduate Student Council.
- Review the Junior Research Workshops (JRW) - AB Independent Work
- Glance through the Independent Work page.
- Independent Work questions? Ask Mikki Hornstein, Independent Work Coordinator, mhornstein (@princeton.edu)
- Undergraduate Program questions? Ask Colleen Kenny, Ugrad Program Manager, ckenny (@princeton.edu)
Where can I find answers to my Computer Science questions online?
A great online source is the Undergraduate Program FAQ.
Ready to declare Computer Science (or would like help deciding)?
Step 1. Attend the AB'25 Open House - TBA.
Step 2. Ready to Declare
Sophomore concentration declaration will be March 30 – April 17, 2023. Go to TigerHub to declare COS. Intended concentrations are processed overnight. The department will have access to your academic records one business day after you complete this form.
*************** You must declare your COS concentration before you can move on to Step 3. *********************
Step 3. Now that you have declared your concentration as COS.....Welcome to Computer Science!
April 2023 - Complete your Departmental Academic Planning Form (DAPF) in Tigerhub. If you require additional advice on courses or independent work, please email the advisers below, which are assigned by last name:
- AB'25 Surname A-J
- AB'25 Surname K-R
- AB'25 Surname S-Z
Step 4. Fall Course Selection
After declaring COS and entering your fall courses into the DAPF, you are ready to select courses for the fall semester. Sophomores will be able to enroll in courses in Tigerhub beginning April 19, 2023.
