<p>well, it is certainly a very small number of graduate students if you compare it to other major universities. Harvard, for example, has 6,000 undergrads and around 9,000 graduate students, I believe. Chicago, for example, the opposite of Pricenton when it comes to grad/undergrad population size, has about 1 undergrad student for every 2 graduate or professional students. The advantage at Princeton is certainly the fact that you probably get more top-notch faculty teaching the "college" students, whereas at a school like Chicago that may be a bit harder (although all profs. in the university are required to teach undergrads every year), yet research opportunities may be easier to get.</p>
