I sent mine around the same time and the score has been in for at least a month maybe more. You may want to email admissions.Don't know about the SAT, but I sent my ACT scores on August 20th and USAFA still says they have not received them.
I have emailed them and ACT multiple times to no avail. ACT says that USAFA has them, USAFA says they do not. Idk what the deal is.I sent mine around the same time and the score has been in for at least a month maybe more. You may want to email admissions.
