<p>Priority application gives you some advantage, more so for A&S than other college. You can get four different decisons: admit, reject, admitted to a different major/college as long as you checked the box in the application for being considered for a different major (mainly you usually get admitted to Division of General Studies which means that for whatever other major you applied you were rejected), or deferred (to Feb). Many do get rejected in December, many get admitted to a different major. Percent deferred can vary widely each year but generally A&S defers less than 25% in December except for some majors (e.g., physics and chemical engineering follow the engineering college). Business defers 70% or more (and many of the others receive a rejection or admit to DGS). Business more than any other college just likes to make most decisions in Feb after all apps are in and it sees the entire pool, which is somewhat driven by the fact that it ends up admitting less than 40%. Engineering often defers close to 50% (and most of those actually end up getting admitted since it has one of the highest admit rates, usually greater than 70%).</p>
