<p>Correct me if I'm wrong, but for posts from different years, some people have said they mailed in abstracts for research they did. Is that still the case or does Princeton have some kind of SlideRoom thing?</p>
<p>I do not believe that Princeton has some kind of SlideRoom thing. They do support art supplements, but it’s online through this shady website (or you can mail it), so I’d expect nothing more than that for research supplements (they don’t seem to mention it anywhere).</p>
<p>Thanks for the response! I don’t know if you’re an applicant, but if you are, on the Common App website under the Writing Supplement section for Princeton, at the very bottom there’s a place where you can attach a file “if you wish to provide details of circumstances or qualifications not reflected in the application.” Do you think I should upload my research paper there?</p>
