Minor in Computer Science
The Minor in Computer Science is offered for students seeking significant knowledge of digital computers without the more complete treatment of a major in computer science. This minor may be taken by any student except majors in the Computer Science degree programs and in Computer Engineering.
Capacity in Core CS Courses
The Department of Computer Science is committed to providing enough capacity in the core courses for our minor (CS 124, CS 128, CS 173, and CS 225) to accommodate all students who are interested and who meet the prerequisites. Students wishing to complete a CS minor are recommended to take CS 124 and CS 225 in the Spring semesters, and CS 128 and CS 173 in the Fall semesters.
Note: Declaring a minor in CS will not give you an advantage in registering for CS courses.
Guaranteed Admission to the Online MCS or MCS-DS
If you complete any CS or CS+X major or a CS minor at Illinois with a GPA of 3.0 or better in the last two years of your undergraduate degree and a GPA of 3.2 or better in CS courses, you are guaranteed admission to our Online MCS or MCS in Data Science (MCS-DS) programs.
Recent UIUC graduates may qualify for an application fee waiver!
