At Columbia, there is a practice called “Skipping Grades.”
According to an article titled “Early Departures: The Experience of Graduating Early” in the Columbia Daily Spectator, it can be beneficial for students to graduate early. If they have credits from the International Baccalaureate program, it might make things a bit easier.
If students want to pursue programs like Columbia Bachelor + Master or Columbia 3-2 and 4-1 Programs within the range of Yagi, this could be a means to achieve that.
