<p>I did some interesting things in high school in pursuit of my passions, things that I feel an adcom might reasonably question. Should I include something to show them the things I've done? I don't want to be an obnoxious applicant who just sends in pics of a bunch of crap to show off, but I also feel that they might appreciate it and perhaps even get a better idea of who I am if I do send something?</p>
<p>You don’t need to send things to prove that you did what you claim, but if you feel that additional material would help the admissions office understand your activities, then you should feel free to send it in. Usefulness should be the criterion.</p>
