" Obama attended Columbia College from 1981 to 1983, after transferring in his junior year from Occidental College"
Columbia College is a separate division of Columbia University. It's essentially an alternative school and it's not even on the same campus.
What in G*d's name are you talking about? Columbia College is the "Ivy League" core college in Columbia University and shares the same campus (116th Street, etc., between Broadway and Amsterdam Avenue) with Teacher's College, the law school, School of General Studies, and on and on. Please get clear before you post such nonsense.
I believe Columbia College is the undergraduate college within Columbia University. Same campus, 116th St.
Much like Radcliffe is a college within Harvard University.
