Sorry to disagree, but Columbia does not have an Extension School with open enrollment. It does have a division of Continuing Education and Special Programs which offers non-degree & degree courses and all degree programs at Columbia have tough admissions criteria. Kelly graduated from the School of General Studies, a traditional, regular ol', sage-on-the-stage, in residence, undergraduate degree-granting division. I don't know where she's pursuing her MBA but it's not Columbia since the Columbia Business School does not offer online degrees!
