<p>opie12, Michigan’s current 6 year graduation rate is 90% (compared to 92% at Vanderbilt). Also, while your 73% 4-year graduation figure seems accurate, you need to keep in mind that the majority of OOS students graduate within 4 years, precisely because of the high cost of attendance. Also, several Michigan programs require more than 4 years to graduate, particularly double majors and Engineering. The reason why students take longer than 4 years to graduate is either personal or curricular. It is seldom because students cannot register for required classes.</p>
