Epo.. check out the posts under boco acceptances class of 2012.. this has been discussed several times
As far as i'm aware, and I could be wrong.. They waitlisted about 30 studens. She should call the school and find out where her name ranks on that list and do what she can to get an acceptance. If she calls and speaks with the right people and conveys to them that BoCo is infact her FIRST choice she could make it happen. It just takes a little persuasive conversation
Best of luck to her!
