Creative Supplement

Hello!
I have a question about the creative supplement for UR. Can I just send them a short story I wrote (scifi, btw), or do they want something else, like just an excerpt from a story? Their website doesn’t really give much information about it.
Also, what’s the writing sample? Is that covered by the essay (CommonApp/why my creative supplement relates to UR) and my creative writing supplement, or is it something else entirely?
(Also, I know this isn’t the essay forum, but if anyone wants to read my common app essay or my creative writing, just say so because I need as much feedback as possible on both of them)

For the creative supplement, sending in an entire story is fine. (If it were novel, then I’d recommend sending several representative chapters. You don’t want to overwhelm your reader.)

The writing sample is a copy of a expository or research (non-fiction) paper you’ve written for class. Send a .pdf or word copy of your final draft so there’s no grade showing on it.

So for the creative writing supplement, could I send an assignment (a prologue) I did for my Literature class? And if so, should I show the grade that I got or not?
