<p>what happens is if a grade is over-enrolled on a class for their freshman year then they figure out what to do with the extra bodies for that year (i know st. mark’s put freshman girls in a diff dorm). Then the next year they just accept less of that group. That’s why schools don’t give that much of a yield for sophomore and junior years because they’re in trouble if they over-enroll but they can just turn to the waitlist if they under-enroll.</p>
