<p>I would like to send my research design along with an explanation of how it works to Princeton. I do not seee a palce for supplementary materials such as the one on the harvard supplement. Does Princeton not want these, or do they want you to put it in additional information?</p>
<p>I'm pretty sure Princeton welcomes supplements as part of the admissions process. I'm not a science-y kid, though, so you'll have to get the specifics from someone else.</p>
<p>Princeton welcomes talented students to send their work along with the application.
The "Arts Background Supplement" should be somewhere on the Common App. I would use that form to send your materials.</p>
<p>If I remember correctly, there's also some optional forms for additional information on the Princeton application. I used the common app, but I didn't run into any problems when I attached extra stuff to the 'optional what else would you like us to know' from the Princeton app along with my other common app material.</p>
