St.Johns Class placement of students

<p>I will be attending St.Johns for the fall semester of class 2013-2014 as an undecided major.?
In saint johns, I was just wondering if the pharmacy students, or students who are top % of their school who are accepted, are put in the same class as the regular students with lower averages (like 2.5gpa put in to a class with a student who has a 4.0 gpa. Is the placement of students in their classes arbitrary or is it based on grades and the major. Please I would really like to know how their system works.</p>
