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?


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.
