Declaring Computer Science for BSE'28 Students

**BSE'28 SPRING 2025 Open House, TBA**



What are the prerequisites for the BSE'28 COS Majors?   

All students majoring in computer science must take three prerequisite computer science courses: COS 126, COS 217, and COS 226. The math requirement is automatically fulfilled by BSE candidates through their general BSE degree requirements. All prerequisite courses must be taken for a letter grade, not PDF. The three prerequisite computer science courses introduce the core concepts and techniques of the field. All three are offered every semester.
How do I know if Computer Science is a good fit? 
  • Review the Class of 2028 - Departmental Requirements
  • Browse the Computer Science website, especially the Undergraduate pages.
  • Why COS?  Advice from the Computer Science Undergraduate Student Council.
  • Ask the Undergraduate Program Manager, Colleen Kenny. You are welcome to send an email
