Thanks for the input, guys. I didn't think the schools were tracking these emails all that closely because in another thread on the Maryland board, "Bear" got the same email my son got, and he's a little old to be a 2012 grad, or even 2011. When he posted that, I thought, "This whole 'You're one of the top prospects in the area' must be a phrase that's tossed around lightly."
And those questionnaires are lengthy. The poster whose son has already filled them out and sent them back... good for him!
