How should I compare my realistic computer science admission chances at UIUC and Carnegie Mellon?

For most applicants, Carnegie Mellon’s School of Computer Science should be treated as the less realistic and more extreme reach, while UIUC computer science is still a very high reach rather than a target. Both programs attract applicants with exceptional grades, rigorous math and science preparation, and substantial computing experience, but Carnegie Mellon CS has an especially concentrated pool of applicants seeking one of the most internationally recognized undergraduate CS programs.

At UIUC, your intended major matters substantially: computer science in the Grainger College of Engineering is far more selective than admission to many other UIUC programs. Evaluate yourself against applicants with top-level preparation in calculus when available, physics, advanced computing, and sustained academic performance, not against UIUC’s overall admission picture. Because UIUC’s CS review is major-specific, listing it as a reach is appropriate even for students whose credentials would be very compelling elsewhere at the university.

For Carnegie Mellon, separate the university from the School of Computer Science. CMU SCS is not simply an admission to a large CS department; it is a small, highly sought-after school with an applicant pool that often includes students with unusually deep technical work, such as meaningful research, substantial independent projects, high-level competition involvement, or real-world software impact. Those activities are not requirements, but they illustrate why excellent grades and test scores alone do not make admission likely.

Use your transcript first: compare course rigor and grades in the most advanced math, science, and computing courses available at your school. Then look for evidence that your interest in CS is sustained and specific, such as a project developed over time, a technical job or community contribution, research, or an activity where you solved a real problem. UIUC may be the comparatively more attainable of these two reaches, but a balanced list should also include several colleges where your academic record is closer to or above the typical admitted student profile for CS.
