<p>Well you put Columbia and Stanford on your list so I figured you were aiming for the top ;)</p>
<p>Penn and Yale have requirements that are less rigid than Chicago or Columbia (that being said I'd still prefer Chicago/Columbia because I am a firm believer that everyone in a republic should know the great works of Western civilization before he/she can be called Educated).</p>

<p>A cursory glance reveals that Yale's requires a more intensive language focus while Penn's requires a greater focus on economics.</p>
