Urgent: need help with writing sample for University of Rochester!!!

Would it be best to submit a semi-good (7/10) research paper, a good (8/10) lotr “fan fiction” creative piece which is based off the book which i read in a class, or a very good (10/10) DBQ that i did for ap world? i believe that these are my three best works throughout high school that have all been graded. which one should i submit? do you think they would prefer the research paper even though my dbq was better?

That depends on the college, really. But usually and generally, I would go with the research.

I would agree, since DBQs tend to be timed writing pieces for tests.
