I am about to call the school that wait-listed me. I would like to hear some advice on what I should say. Am I supposed to express my interest via a oral statement, or just say "Thank you for reviewing my application, and I just want the committee to know that I am very interested in XXX?" I have written one 300 words letter of interest before. I don't know if it would be too long or even annoying to say the same thing in a phone call. What did you guys say when you call your schools to express your interest?
