My Advice
Focus your energy on research depth rather than a marginally higher GRE, because Caltech admits people who can already produce original work. Identify two or three professors whose labs match your interests and reference them in your statement. Secure recommenders who can speak to your research firsthand, since generic letters rarely survive this pool.
