Yeah, I got a 33 composite on my ACT (34 English 33 Math 36 Reading 30 Science) and decent scores on the SAT (1410 math + reading), did very well on the fitness test, and have lots of ECs, and have still yet to get a LOA. Needless to say, I'm pretty bummed.
However, the AFA has yet to update my SAT scores yet, so I'm going to call tomorrow and make sure they've received them; once my profile gets updated, it gets scrutinized again and gives me another chance for an LOA.
