SAT superscoring question

I am currently a junior. Does UNC take into consideration my highest SAT from an individual sitting, or is my super-scored SAT all that matters? I am in-state, and my super-score is a 2080 (700 CR, 720M, 660W).

However, I prefer the ACT. I scored a 31 in March (no studying, blah blah blah lol), and I feel confident I can raise it to around a 33. Should I roll with the ACT… maybe submit both? I’m not sure at this point. Thanks!

They do super-score which gives you the highest score. I would submit whatever score is the highest.
