Is Carnegie Mellon or Purdue harder to get into for computer science?

The main practical difference is that Carnegie Mellon’s School of Computer Science is a much smaller, intensely selective undergraduate program, while Purdue enrolls a larger CS cohort but still has limited space and major-specific competition. Both require excellent preparation in math and science, but CMU SCS is typically viewed as one of the hardest computer science programs in the country to enter. Purdue CS is highly selective as well, especially for students applying directly to the major.

At Carnegie Mellon, applicants are evaluated for admission to the School of Computer Science itself, so strong grades alone are rarely enough. The most compelling applicants usually pair top-level quantitative coursework and performance with meaningful technical depth, such as substantial programming projects, research, advanced problem-solving, or unusually sustained work in computing.

Purdue’s computer science program also receives far more qualified applicants than it can accommodate. A rigorous senior-year schedule, particularly through calculus and strong science courses, remains important at both schools.

For admissions difficulty alone, Carnegie Mellon is harder to get into for computer science. Purdue should not be treated as an easy alternative, but it is a more realistic target than CMU SCS for many otherwise strong CS applicants.
