I took a moment to read all threads from the OP. I see a chameleon -simply all over the map on who they say they are and where they say they are and who changes stated goals from post to post based on which forum they are posting in, like Tarzan swinging from vine to vine. So before any of you fall for this as hard as I did, here are a few data points.
Actually at a prep school. Implied he accepted an appointment and was at USMA and was struggling there. Maybe he has a contingent acceptance if he can get through a prep year. OP, prep schools are honorable. Many who attend will go on to the academies - quite a few will not.
Stated "Knows how to succeed at an academy" IMO implying he has experience at one, Doesn't appear to be accurate.
Stating DS regrets leaving ROTC for a USMA appt and consistently just wants to go to go back to ROTC.
Then days later posting about about an interest in going to the Air Force Academy from his prep school.
Implied advanced standing / finishing junior year in AROTC then months later implied being at a sophomore when leaving this for a USMA appt.
I'm curious if we'll see a soap-opera like response which clarifies he has twins or some nutty attempt to justify the multiple conflicting representations of who they are. Reminds me of Caddyshack when Danny would say "I've always wanted to be a" priest, rabbi, lawyer, golf pro judge, etc. based on who he was speaking with.
Hopefully soon OPs son will be at an academy, living one of his dreams. Good luck to him. Thanks for his willingness to serve.
