<p>what is Columbia's average class size?</p>
<p>this is too vague a question.</p>
<p>intro sciences will be huge, as is the case for nearly all schools.
core classes, english are quite small though.</p>
<p>Columbia</a> University in the City of New York</p>
<p>the answers are there</p>
<p>(to add to lville tho, any intro course will be upwards of 75-150ppl but anything beyond that will fall drastically to 20-30, maybe 40 if it's for a popular major)</p>
