What is the difference between Columbia College and University?

• I know that Columbia College exists on the university campus...but what is the difference? Is it considered to be a sort of junior college? Do they both offer the same degrees? Is the only difference that Columbia College requires full-time enrollment?

• Answer:

  Not to be confused with Columbia College in Chicago, which is completely unrelated to Columbia University, this Columbia College is the basic undergraduate school of the university (Engineering is separate, and there is a different undergraduate program for nontraditional students called the School of General Studies, but everyone else goes through Columbia College). Other schools following the same model are Harvard University, with its Harvard College, and Georgetown University, with Georgetown College.
