<p>MBA Adcoms do not usually keep track of such information. The only one I know of that does is Wharton. And let me tell you, the quality of one's undergraduate institutions matters... A LOT. Here is a list of the most popular undergraduate institutions of students who entered Wharton in 2004:</p>
<h1>1 University of Pennsylvania 50</h1>
<h1>2 Harvard University 30</h1>
<h1>2 Princeton University 30</h1>
<h1>4 Cornell University 25</h1>
<h1>4 Stanford University 25</h1>
<h1>6 Duke University 20</h1>
<h1>7 Columbia University 15</h1>
<h1>7 Dartmouth College 15</h1>
<h1>7 University of California-Berkeley 15</h1>
<h1>7 University of Michigan-Ann Arbor 15</h1>
<h1>7 University of Virginia 15</h1>
<h1>7 Yale University 15</h1>
<h1>13 Brown University 10</h1>
<h1>13 Georgetown University 10</h1>
<h1>13 Massachusetts Institute of Technology 10</h1>
<h1>13 University of California-Los Angeles 10</h1>
<h1>13 University of Chicago 10</h1>
<h1>18 Northwestern University 5</h1>
<h1>18 New York University 5</h1>
<h1>18 Penn State 5</h1>
<p>No other university contributed more than 4 students to Wharton's entering class of 850 students. As you can see, with the exception of PSU, all of the schools that had 5 or more representatives are top 25 universities. And those 20 universities made up 350 of the 850 students who entered Wharton. The remaining 500 Wharton students came from over 200 undergraduate institutions.</p>
<p>Obviously, regional preferences dictate that more Ivy Leaguers will apply and choose Wharton (or other Ivy League MBA programs) which explains why the Ivies are so popular at Wharton. At Kellogg , Chicago and Michigan (3 of the top 7 or 8 MBA programs in the nation), midwestern universities like Northwestern, Chicago and Michigan are the most popular. At Haas and Stanford, West coast universities like UCLA, Cal-Berkeley and Stanford are the most popular. But by and large, the quality of one's undergraduate insitution matters. Not as much as work experience, but as much as GPA and GMAT score.</p>
