How can I assess whether Carnegie Mellon or Caltech is a realistic reach for me?

Treat both Carnegie Mellon and Caltech as reaches, even with an excellent record, and assess them by the match between your evidence and each school’s academic culture. Carnegie Mellon is especially useful to evaluate through the strength of your preparation and sustained work in the specific undergraduate school or program you would select, particularly the School of Computer Science. Caltech demands similarly exceptional math and science preparation, but its small, intensely STEM-centered environment makes intellectual depth across science and math especially important.

For Carnegie Mellon, compare your transcript to the most demanding math, computing, and science courses available at your school, then look for proof that computer science is more than an interest. Strong signals include substantial programming projects, research, technical leadership, advanced coursework, or work that shows how you think through difficult problems. The application should also make clear why CMU’s particular approach to computer science, not just its reputation, fits your goals.

For Caltech, ask whether your record shows genuine excitement for foundational mathematics, physics, chemistry, or other sciences alongside computing. A student whose profile is almost entirely coding-focused may be a less natural fit than someone who pursues computational work while also relishing theoretical and scientific questions. Caltech’s application is a place to show curiosity, collaboration, resilience with hard problems, and specific intellectual engagement rather than a long list of activities.

Use your school context honestly: being near the top of a rigorous course load is more meaningful than comparing yourself to anonymous applicants online. Have a counselor or teacher who knows your academic level assess whether your work stands out among past applicants to highly selective STEM programs. If both applications can be completed thoughtfully, applying to both is reasonable, but build a balanced list because neither can be treated as predictable.
