kay1123 - don't take this the wrong way, but if your fitness level isn't sufficient to pass the CFA, then you should not be at a SA. If this failure was due to an injury, you can heal and reapply next year informing the admissions board of your reasons for failure. If, however, you failed because you do not meet the minimum fitness standards, then a rejection does you a favor as you would have struggled to meet the minimum fitness standards at the academy and as an officer. I suggest that you get to work on your fitness - hire a trainer, join a CrossFit gym, whatever it takes - and reapply next year. You can tell the admissions board next year about your biggest failure and greatest achievement in overcoming whatever fitness deficiencies you have and turning things around. If USNA is your goal, then get to work. Good luck.
The CFA is a requirement. My DD passed the CFA but AF wanted a higher score. She did & all was good but the fact is the CFA is just a stepping stone. Now at USNA the physical aspect is so much more. Best be ready or you’ll be crushed, good luck.
