Congrats pscherer, welcome to the class!
jnljinson I would echo what pscherer said. If Notre Dame is where you really want to go then you can't give up. I know how you feel as I was declined 5 times from the undergrad I wanted to go to before I was accepted on my 6th and final attempt. Notre Dame is not a purely statistical school. Personality, class composition, diversity of experience, and many other things come in to play. As a side note I know for a fact that they watch this board and I am sure they can understand the disappointment in being waitlisted, but try to stay relaxed and keep moving. Think about it like football, if the QB is getting pressured and stops moving his feet then it is all over. So keep moving those feet and keep striving to get where you want to go.
