What Caltech is really asking
What is the real origin of this interest, in 200 words?
The mistake most applicants make
Describing the field. They want the moment it became yours.
Do this instead
One moment or problem that started it, one thing you did about it, one question you still have. Specific beats grand.
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.
