<p>Since Princeton's supplement doesn't include space for additional materials (music/science, etc), should I still send in a supplement if I personally feel it is a significant piece of work? Would my action aggravate the admission officers?</p>
<p>No, go for it.</p>

<p>Did anybody submit any science supplementary materials? Would you mind PMing me what you submitted and the techniques used so that I can see whether mine is worth sending in?</p>
