Now I remember hearing the same last year. I forgot about the reason I understood then. My other DS is applying this year and he too is not getting any reply; remembering the rule puts me in comfort. Thanks for the reminder.
I also agree with role of the coach after having sent my DS. Where my DS is going (very small), the coach is also a teacher and a dorm master. My DS had to try out for V and JV, both of which he failed to get in by a hair, even though he came with the expectation of a recruit. He is in 3rd, and he loves it because he makes or breaks every game with 90% play time (at V or JV, he would have been on bench most of the time) and all his freshmen dorm buddies are in the same team. So you never know how things will unfold.
All in all, I cannot help but thinking sending DS to boarding was the best thing that happened to both me and him.
Just relax and enjoy until the good new arrives.
