SAT single sitting score?

I was wondering if UNC takes test scores into consideration if they were all in one sitting. I know they superscore but is there any advantage given if you get a score on one single test rather than superscore it across multiple tests? I am asking because I got a 1500 in May and am wondering as an out of state applicant if this will give me any benefit. UNC is my absolute dream school and I’m gonna need all the help I can get haha.

All I can say is I asked Davidson, Kenyon, and Denison this question and ALL OF THEM said it made NO DIFFERENCE if the score was in (1) sitting or a superscore.

I wanted to believe more weight was placed on one sitting, but I guess not!!
