<p>BTW, the prefix listings for the courses are even more confusing. I believe letters are assigned to a course depending upon which division of the university sponsors the course. If a course is sponsored from Columbia College, it will have the prefix C and although it is often open to students from other divsions of the university (Barnard, Gen Studies, SEAS) it may not satisfy certain requirements of those other divisions especially if it is a requirement for a major. It gets even more confusing. V courses are co-sponsered with Barnard and often satisfy requirments for majors on both sides of Broadway. Intro math course in Calculus are a good example of this. W courses are inter-faculty sponsored and can come from any undergraduate or graduate division in the univerisity and often satisfy a large number of requirements from departments across the entire campus. The History department is a good example of this where almost all of their course are W. This is all very confusing at first but becomes second nature after some time working with the catalog, list of classes, and major requirements.

<p>The letter isn’t terribly important. I believe there were three different “listings” of Gen Chem last semester - C1403, W1403 and F1403. There was no discernible difference. (Oh yeah, the prefix E refers to classes offered by the engineering school.)</p>
