<p>Oberlin is a phenomenal school with a very long and distinguished history. I would presume the Conversatory plays a role in the 4 year rate, similar to Rochester. What hasn’t been mentioned is the type of kids that go to Oberlin. My impression is that Oberlin attracts extremely bright, mostly very liberal students who do not necessarily comply with convention. Maybe some take an extra semester or so because of some qualitative experience. Maybe there’s actually an additive reason. Maybe it’s actually BECAUSE the students are talented and free-spirited. At any rate, I am sure it is not because of the relative quality of the institution or any inherent extra difficulty graduating in 4 years compared to its peers.</p>
