I applied to SLE and NASS in January, I haven't heard back from either, there is the "official" cut-off date, but how late would last-minute acceptance letter be submitted? Also is there any way to update SAT scores for NASS? SLE has the whole portal system, so updating is easy.
I just got my NASS acceptance email today (I am declining, it conflicts with finals week and both of the SA summer programs I already committed to), the cut off for Navy isnt until April I think. I think if there isnt an easy portal for Navy to change your scores like there is for USMA, and you didnt send a score report to the Naval academy directly from the SAT, you should email admissions. If you cant find the email for admissions I can give it to you over direct message.
