<p>I'm a Princeton student whose spent two summers at Columbia (Princeton does not offer summer classes), and went to a competitive high school in Manhattan and so had 30 classmates in my graduating class matriculate at Columbia. Based on that I wil say:</p>
<p>Columbia is one of the WORST experiences in terms of administrative red tape and nickel/diming you to death. I don't know what the deal is with the administrators but they seem inept, shameless, and lazy. For example, my summer classmates apartment had a fire in it (she is a full time Columbia student), and it took the administration two months to resettle them. They were people basically living in the library because of the administrations ineptness. </p>
<p>The day I was to come in for registration, they decided to close the registration office early, but neglected to tell me this when I called them two hours prior to taking an hour train and half ride to campus. </p>
<p>They also seem to get extreme pleasure out of nickeling and diming you to death at Columbia, for example, charging you 10 cents a page for printing on the laserjets.</p>
<p>Columbia currently has a better arts program and chemistry program.</p>
<p>Princeton has a better social sciences (esp. economics) program, much much better engineering school, better life sciences program, better english and comparative literature program, and better hard science program (other than chem).</p>
<p>Princeton has realized this and is building a new chemistry building/program and arts center/program to remedy the situation.</p>
<p>Some other aspects:
Columbia is very liberal, less so than Brown, but still very liberal.
Princeton has the full spectrum of politics, I would say conservatives represent 35% of campus, liberals 35%, and 30% are libertarian types.</p>
<p>Columbia's sports teams are a joke whereas Princeton's sports teams are not.</p>
<p>Columbia is in NYC, and a 10 minute train ride to midtown, 15 minute train ride to downtown. whereas Princeton is an hour and 15 minutes from NYC and Philly.</p>
<p>Columbia is surrounded by a ghetto to the north and the east (don't go running in Morningside park or north of 125th street unless you wish to be mugged or approached by crack dealers).
Princeton is surrounded by investment bankers and pharma professionals (watch out, you might be approached by someone trying to sell you some stock).</p>
<p>When I stayed over for prefrosh weekend I also thought that Princeton students were very preppy and stuck up. I actually matriculated elsewhere but changed my decision. Best decision I ever made. Princeton students are actually quite friendly and most are not at all conceited or stuck up. There are many very wealthy students (I would say that out of the 25 hallmates in my entryway, 10 of them had parents with net worths over $15 million), but they are all friendly and sociable, even to a middle class kid like me.</p>
<p>I think the preppiness stuck up factor that your son might have perceived stems from the fact that princetonians have a strange affinity for polos or blazers pretty much wear them all the time.</p>
<p>Columbia's dorms have roaches. Princeton's do not.</p>
<p>Undergraduates run Princeton's campus, not sure about the situation at Columbia but I see their GSB students all over the place.</p>
