My niece has decided she wants to go to Princeton. She has the grades and test scores, but I know more is needed. She has led an interesting life, lived in several different countries for example. Her "extracurriculars" likely need beefing up; she has done a bit of volunteer work but not much, and is on a local equestrian team. Any ideas on how she can beef up that application in a hurry (she is a junior)?
