@kaia @glent @chjara not quite. In US parlance, Universities are a composition of colleges. I went to Northeastern University, but my degree is from Khoury College of Computer Sciences. I attended classes from other colleges in the NU umbrella - for example, College of Arts, Media, and Design.
If I went back to Northeastern for a graduate Computer Science degree, I would still be a student at Khoury - colleges still run the graduate programs.
