Out of all applicants that apply out of high school, what determines who gets an appointment versus spending a year at prep? I understand that there's a specific number of slots allotted to preppies that have done well at prep school. If it comes down to choosing between a qualified high school senior and a preppie, who does the admission board give the appointment to? Is going to a prep school comparable to attending a SAT boot camp to boost your score? It seems like spending a semester at a prep helps a lot in getting a slot to a SA. I just don't like the part where none of the classes are credited if one does not get a coveted appointment.
