<p>What's Columbia's pass/fail system like: how many classes can you take pass/fail, which classes, etc. Thanks guys.</p>
<p>Do they have one? I thought only Brown had such a system.</p>
<p>I think you are allowed 2, non-core classes per semester.</p>
<p>I believe it's one class per semester, not counting classes that are only offered p/np. </p>
<p>Individual departments have their own rules, however, about whether or not you can take any classes for your major p/np. (For example, the first economics class Principles of Economics may be taken p/np and still counted toward the major, but all other classes required for the major must be taken for a grade.) So, combined with core classes which must be taken for a grade, that somewhat limits the option.</p>
