I'm currently a junior starting my application process. I am also planning on attending NASS. I am curious about the Letters of Assurance. Would this guarantee admissions for a candidate if they qualify/complete the rest of their applications (sort of a conditional acceptance?)? Has there been a case in which a LOA was given out but the candidate was not accepted in the end? Also, what would be the qualifications of a typical student receiving a LOA (stats, academics, GPA, SAT, etc)? Thanks!
