Princeton Creative Arts and Humanities Seminar - Process?

<p>Also posted in General Admission section -- sorry for the duplication. Son was just advised his public high school was nominating him for this year's Symposium. I know his school sent someone last year as well. Anyone know how many of those nominated (one per school, it seems) actually get an invitation? Does anyone know the process after schools nominate their candidates? Should my son provide his counselor with a resume or contact Princeton or anything? Thank you</p>
