<p>At Columbia, how easy is it to access your professors outside of the classroom, specifically science professors? Are they in and out of the lecture hall, or do they post regular office hours? Are they very helpful to undergrads, or do they just care about graduate work and research?</p>
<p>On a different note, how big of a deal is it to be studying in NYC? How often does the average Columbia student go into mainline Manhattan and enjoy all that the city has to offer?</p>
<p>Thank you!</p>
