What Caltech is really asking
Do you care about how you solve things, not just whether you did?
The mistake most applicants make
Telling a success story. The prompt says process matters as much as outcome, so a failure works.
Do this instead
One problem where the outcome was uncertain or bad. Show the approach, the choices you made under uncertainty, and the one thing you would still defend. Honest process beats a clean win.
How to spend 200 words
200 words is two or three short paragraphs: the specific moment, what it revealed or changed, and why it points to this school. Cut any sentence that could appear in another applicant's essay.
