<p>as a strong EC for Caltech? and not the typical USAMO, Siemens, etc... or what EC really stands out to the admissions officer of Caltech?</p>
<p>There is no right answer to this - just follow your passions! Typical Techers have done Robotics, Math clubs, chess clubs, science olympiads, Rubiks competitions, Quiz Bowl, Academic decathalon, track, basketball, water polo, unicycling, youth orchestras, Key club, Debate teams, marching band, and on and on.</p>
