Or can I just send the higher of the two?
Do the requirements for applicants state “OR”?
It has real meaning.
My understanding is that USNA super scores. They look at your best score although I don’t know if they do a super score across ACT and SAT. My advice is to send all scores.
Send all of the scores that you can. USNA looks at everything and takes the highest score submitted in each area. Lower scores that are not used do not hurt you so send everything.
