I am currently halfway done my CalTech app, and I'm writing up this "list of publicaitons". Problem is: I haven't got any! If, for example, my name went on a poster that was presented at a conference (the poster was submitted and refereed), then does that count as a publication? If not, where else in my application might I mention this?
Also, whats up with the "List of Significant Extracurricular Activities"? What do they want to hear in this section? I can't really think of any extracurricular activities that are relevant to physics...
