Thank you both. Falcon, we were told it is a very positive sign as admissions likes his profile. And yes Pima, being realistic we realize it is just one more necessary step, one of hopefully more to come... (or not)
Yes, Plans B-D are in place, along with his MOC nomination... (a welcome step). DS had passed the Fitness Assessment at Summer Seminar with respectable numbers, but decided he wanted to max out on the CFA and he did that yesterday. So now he waits and works at school and other service commitments until he hears a decision.
On a personal note, attending a SA is a new life path, as of his invitation to 2015 USNA Summer Seminar and then CVW, and we are doing our best to change gears and support him in his dreams and desires to serve the country. His non SA-hopeful friends are surfing through their senior year, done with school by noon and hanging out at the beach--as you know, there is none of that going on here. We feel very blessed that DS has had this amazing and singular "college admissions" experience. All the other college apps were a breezy walk in the park after this. My husband and I have loved watching DS lead out, be so driven toward a goal, and to take charge of the future he has chosen. He has done his best (and then some), now come what may.
Thank you again for your time and advice.
