<p>I have the bulletin right in front of me, so I’ll check.

The letter refers to which of Columbia’s many, many schools/divisions offers the course. Most of these are graduate schools, so we don’t care about them.</p>

V Interschool course with Barnard
W Interfaculty course
Z American Language Program</p>
<p>Most of our classes will be V or W and some will be C (or E if you’re in SEAS). I think a C class is a class that Barnardians can’t take, and the same might be true of an E class. V classes are obviously open to Barnardians and I suppose W classes are too. A V course is probably within one department, while a W “interfaculty” course is interdisciplinary. But I’m just speculating here.</p>
<p>edit: I think the C courses are primarily Core classes and intro seminars that are prereqs for majors. Most other CC courses are W and V, but I still can’t tell what the difference is. The W courses don’t all seem to be interdisciplinary, and I’m not sure whether Barnardians are allowed into them!</p>
