21% 4-year graduation rate...is this a bad sign?

<p>I believe the retention rate is around 84% (not sure of the exact number) but I am especially concerned because I would like to double major in psychology and Spanish as a pre-med so if getting classes is a problem then it would take me FOREVER to graduate.
I hear that U of Cincinnati does have a pretty large co-op program. Perhaps that is the reason.</p>

<p>thanks for all the help guys!</p>
