Application Strategy

Strategy tips for applying to California Institute of Technology

The first 2 tips apply to all applicants. Your personalized strategy requires your profile — build your free list to unlock it.

Extracurriculars
Caltech values genuine obsession with math and science over a broad list of activities, so go deep on research, competitions like USAMO or Putnam, or independent projects in physics, chemistry, or biology. Admissions wants to see that you would thrive in a place where science is the culture, not just a subject.
Essay Strategy
Caltech's essays ask you directly about your excitement for science and math, so write about a specific problem or idea that kept you up at night, not a vague passion for STEM. Avoid generic statements about wanting to cure disease or explore space and instead get technical enough to show you already think like a scientist.
