Congratulations to your son, kpforson! That's great news!
db10 A conditional appointment can be given with the condition being a successful completion of the CFA. I know this because our daughter got one 2 years ago. (Wow! That time flew by!) However, she was very athletic, multiple varsity letters and team captain 3 times. So it was a pretty good bet that she would pass with flying colors.
I don't know about getting a conditional appointment for low SATs. I tend to doubt it. I'd guess that they would want to be certain of you academically before offering one.
Good luck with application!
